Updated Daily

Quantum annealing represents the earliest commercialized form of quantum computing, using quantum fluctuations to find optimal solutions to combinatorial optimization problems. D-Wave Systems has deployed systems with 5,000+ qubits (Advantage processor) accessed via cloud and installed at research institutions, government labs, and corporations.

Unlike gate-based quantum computers that execute algorithmic instructions, quantum annealers solve problems by mapping them onto an Ising model or quadratic unconstrained binary optimization (QUBO) formulation. The quantum processor evolves from a superposition of all possible states toward the ground state of the problem Hamiltonian.

India's Quantum Annealing Landscape

India's enterprise technology sector explores quantum annealing through cloud access to D-Wave systems. The National Quantum Mission focuses primarily on gate-based quantum computing hardware development rather than quantum annealing hardware, but optimization applications using quantum annealing fall under NQM's broader quantum computing applications scope. Tata Consultancy Services (TCS), Infosys, and other IT majors develop quantum optimization solutions for Indian enterprises using hybrid quantum-classical approaches.

Key Advantages

Key advantages include mature commercial technology with 10+ years of cloud availability, massive qubit counts (5,000+), specialization for optimization without requiring full error correction, and established application ecosystems. Limitations include narrow application scope (optimization only), no quantum error correction, and restricted connectivity requiring problem embedding overhead.

Recent Developments

Recent developments include D-Wave's Advantage2 prototype experimenting with higher connectivity (Zephyr topology) and error-reduction techniques.

Scaling vs entanglement in measurement-induced phase transition for non-integrable systems

--> Quantum Physics arXiv:2608.21578 (quant-ph) [Submitted on 21 Aug 2026] Title:Scaling vs entanglement in measurement-induced phase transition for non-integrable systems Authors:Paranjoy Chaki, Protyush Nandi, Subinay Dasgupta, Ujjwal Sen View a PDF of the paper titled Scaling vs entanglement in measurement-induced phase transition for non-integrable systems, by Paranjoy Chaki and 3 other authors View PDF HTML (experimental) Abstract:We find that the measurement-induced phase transition generated by deterministic global measurements, previously observed in the integrable transverse-field Ising model (TFIM), persists in non-integrable variants of the same. To address this question, we consider the TFIM with longitudinal field and the axial next-nearest-neighbor Ising (ANNNI) model. We show that both the survival probability and the bipartite entanglement entropy consistently capture a transition between area-law and volume-law entangled phases for two distinct initial states: a product state with all spins polarized along the transverse direction and a Greenberger-Horne-Zeilinger (GHZ) state. Finite-size scaling reveals a pronounced initial state dependence: for the polarized product state, the transition point follows an inverse-square-root scaling with system size in both non-integrable models, consistent with the integrable TFIM, whereas for the GHZ initial state, it deviates from this scaling and approaches zero considerably more slowly in the non-integrable models than in the integrable TFIM. These results establish the robustness of measurement-induced transitions under deterministic measurements against integrability breaking while highlighting the crucial role of the initial state in governing their scaling behavior.

Monte Carlo simulations model complex quantum interactionsquantum-computing

Monte Carlo simulations model complex quantum interactions

Researchers at Swinburne University of Technology are promoting transparency in quantum research by making their data and simulation codes openly available via Harvard Dataverse, created in 2025. Published on August 24, 2026, their work details Monte Carlo wave-function simulations used to analyze the coherent coupling strategy for coherent Ising machines, quantum networks designed to solve complex optimization problems. These simulations, involving Hilbert spaces exceeding 107 dimensions, offer a path toward exploring the limits of quantum performance for this NP-hard problem without relying on potentially limiting Gaussianity assumptions. The authors state that quantum computational advantage has been an important motivation for quantum computing researchers. The study was accepted for publication on July 15, 2026. Monte Carlo Wave-function Simulations Model CIM Interactions Researchers are leveraging Monte Carlo wave-function simulations to analyze the coherent Ising machine (CIM) in regimes previously inaccessible to conventional modeling techniques, pushing the boundaries of quantum optimization research. These simulations, conducted by a team at Swinburne University of Technology, utilize Hilbert spaces exceeding 107 dimensions to accurately represent the complex interactions within the CIM, a quantum network designed to solve the NP-hard Ising model. The team’s approach circumvents limitations inherent in master equation methods, which become computationally prohibitive as system size increases, and avoids the inaccuracies of Gaussian approximations when dealing with non-Gaussian quantum states. To facilitate open science and reproducibility, the data and simulation codes underpinning this work are openly available through Harvard Dataverse; Manushan Thenabadu, Run Yan Teh and P D Drummond created “CIM Project Codes for Numerical Simulation, Version 1.1 (2025)”. This commitment to transparency allows other researchers to verify the findings and build upon thi

Quantum Computing Stocks IonQ, Rigetti Computing, and D-Wave Quantum Have Put Wall Street on Notice With This $863 Million Warning

Although artificial intelligence has been driving Wall Street's bull market for almost four years, it's not the only game-changing trend that's capturing the attention and capital of investors. The quantum computing revolution is a potential trillion-dollar addressable market and is exciting investors. As of October 2025, several pure-play quantum computing stocks were delivering breakneck trailing 12-month (TTM) returns. IonQ (IONQ +8.02%), Rigetti Computing (RGTI +11.48%), and D-Wave Quantum (QBTS +8.46%) gained as much 6,200% over the trailing year. Investors who had the wherewithal to put their capital to work in these pure-play companies have been handsomely rewarded. Image source: Getty Images. But things may not be as perfect as the eye-popping two-year gains in quantum computing stocks suggest. Based on the actions of those who know IonQ, Rigetti, and D-Wave best, a worrisome message has been sent to Wall Street. Insiders at IonQ, Rigetti, and D-Wave have put Wall Street on notice Even though dozens of analysts closely monitor these pure-play quantum computing stocks, no one understands the nuts and bolts of these companies better than their insiders. An "insider" is a high-ranking executive, board member, or beneficial owner of at least 10% of a company's outstanding shares who may possess non-public information. Typically, insiders are a public company's biggest cheerleaders. But sometimes their actions speak louder than words. Securities law requires that insiders report any purchases or sales in their company's stock (including option exercises) via Form 4 within two business days. This also allows everyday investors to track whether insiders have been buyers or sellers of their company's stock.

Theory and experiment agree on quantum system’s quick change

Researchers from China and Luxembourg have experimentally validated a theoretical framework for understanding rapid changes in quantum systems. Using a trapped-ion quantum simulator, the team probed quenches initiated from a critical point, revealing how defect statistics scale with the speed of the change. The work demonstrates that these defect distributions exhibit predictable, universal behavior, establishing quench-depth scaling as a benchmark for studying quantum dynamics far from equilibrium. This research addresses a fundamental question in physics: determining when universal behavior emerges in complex quantum systems. Quantum Quenches Initiated at the Critical Point Laboratory experiments utilizing trapped ions in China and Luxembourg have provided detailed validation of theoretical predictions regarding rapid changes in quantum systems, specifically those initiated from a critical point. Researchers meticulously probed the creation of defects, localized disturbances, during these quenches, revealing how their distribution behaves under varying conditions. The study centers on the transverse-field quantum Ising model, a system frequently used to model magnetic materials and a cornerstone of condensed matter physics. Chen-Xu Wang, University of Science and Technology of China, and colleagues employed a trapped-ion quantum simulator to induce rapid transitions in this model, starting the process precisely at its critical point, a state of maximum instability. This precise starting point allowed for detailed observation of how defects form and evolve as the system is driven away from equilibrium. The cumulants of the defect number distribution, a measure of their statistical properties, exhibited universal scaling with the depth of the quench, demonstrating Gaussian behavior at leading order with systematic corrections at higher levels. A key finding revolves around the scaling of defect density. The research demonstrates that, contrary to some earlier predic

No quantum advantage (yet) in the world of tensor networks

By joining the legs (indices) of each tensor, it is possible to encode the Hamiltonian or the state of a many-particle system. (Courtesy: Lucy Reading-Ikkanda/Simons Foundation)"> Tensor networks pictographic scheme Each tensor is represented by an array of dimension N, that matches its number of indices. By joining the legs (indices) of each tensor, it is possible to encode the Hamiltonian or the state of a many-particle system. (Courtesy: Lucy Reading-Ikkanda/Simons Foundation) Researchers at the Flatiron Institute in New York City have used a new tensor network (TN) scheme to simulate how Ising spin glasses evolve in time. In many cases, their classical method is more accurate than the latest quantum annealers running the same problem. The results scale in two and three dimensions and raise the bar in the ongoing competition between classical and quantum computers for simulating many-particle quantum systems. Classical versus quantum Quantum many-particle systems provide a good way of comparing computational techniques because their complexity grows exponentially with the number of particles. In theory, quantum computers hold an advantage rooted in entanglement and superposition. In a classical computer, the spin of a particle (up or down) is encoded in bit that is either zero (down) or one (up), but never both. In a quantum computer, the spin can be encoded in a qubit holding a quantum superposition of up and down. This is a much more natural way to represent what the simulated system is actually doing. Recently, a team of quantum computing researchers used the D-Wave’s Advantage2 quantum annealer to simulate Ising spin glass dynamics and claimed that classical computers could not match their results. But now, Joseph Tindall and colleagues at the Flatiron Institute have shown that a classical scheme can do just as well -and sometimes bet

D-Wave Quantum vs. Microsoft: Which Is the Better Quantum Computing Stock to Own for the Next 5 Years?

Quantum computing has significant potential to transform a host of technologies, including cybersecurity, artificial intelligence, materials science, and drug discovery. But it's still in a relatively early stage of development, which makes it difficult to guess now which quantum computing stocks might be winners over the long term. Two companies on many investors' quantum computing radar are pure-play D-Wave Quantum (QBTS -6.42%) and tech giant Microsoft (MSFT +0.27%). Given where the quantum computing market is right now, and considering Microsoft's financial advantages, Microsoft stock is the no-brainer winner. Image source: Getty Images. What's happening with D-Wave right now? I get the appeal of owning a piece of D-Wave. At face value, who wouldn't want to invest in a leading quantum computing company that's betting everything on its ability to develop some of the most advanced computing systems ever to exist? The company has recently scored some meaningful wins, too, including a 1,120% increase in bookings to $35.5 million in the second quarter. Bookings are potential revenue, not actual sales yet, but they are a good indicator that customers are very interested in D-Wave's quantum annealing technology. AT&T is one such customer that has just agreed to expand its use of D-Wave's quantum computers, and may use them for "complex optimization challenges across its network operations." The telecom will experiment with the tech to improve its outage detection and response, manage technician routes, and plan new network expansions.

Basis-update and Galerkin time integration in canonical matrix-product-state form

--> Quantum Physics arXiv:2608.16994 (quant-ph) [Submitted on 17 Aug 2026] Title:Basis-update and Galerkin time integration in canonical matrix-product-state form Authors:Maximilian Fröhlich, Richard M. Milbradt, Martin Eigel, Aaron Sander, Robert Wille, Christian B. Mendl View a PDF of the paper titled Basis-update and Galerkin time integration in canonical matrix-product-state form, by Maximilian Fr\"ohlich and 5 other authors View PDF HTML (experimental) Abstract:Matrix product state algorithms must enlarge their bond spaces as entanglement grows and compress them to control cost. We formulate basis-update and Galerkin (BUG) time integration as a sequence of canonical MPS sweeps for Hamiltonians represented as matrix product operators. We show when two natural basis updates produce the same trial space and when transporting coefficients between successive bases preserves the represented state. Under these conditions, the existing first-order error bound for uncompressed tree-tensor-network BUG also applies to the alternating-endpoint MPS schedule. We verify the uncompressed implementation against an independent six-site calculation. We then compare BUG with two-site TDVP for 16-site transverse-field Ising and Haldane-Shastry dynamics. At matched timestep and truncation settings, BUG performs fewer local exponential actions and has lower runtime. These settings do not produce equal accuracy. The runtime versus accuracy curves cross for the Ising model and are close for the Haldane-Shastry model. The comparison therefore identifies model-dependent trade-offs rather than a general advantage for either method.

An error-mitigated quantum annealing solution for the weighted Max-Cut problem on a cubic lattice

--> Quantum Physics arXiv:2608.15094 (quant-ph) [Submitted on 15 Aug 2026] Title:An error-mitigated quantum annealing solution for the weighted Max-Cut problem on a cubic lattice Authors:Y. S. Yang, P. Tyson, A. B Murphy View a PDF of the paper titled An error-mitigated quantum annealing solution for the weighted Max-Cut problem on a cubic lattice, by Y. S. Yang and 2 other authors View PDF Abstract:The weighted Max-Cut problem is an NP-hard problem with application implications. It is investigated on a cubic lattice with 113 nodes and mixed-signed random edge weights. For a fixed upper bound on edge weights, it has been demonstrated that the computational difficulty increases as the lower bound on edge weights becomes more negative. The solution time for the problem using a novel error-mitigated quantum annealing approach is compared with standard D-Wave quantum annealing (QA) and BQM hybrid solvers, as well as various classical solvers. For the QPU-embeddable weighted Max-Cut instances with mixed-signed edge weights, it has been quantitatively demonstrated that the SEMO (spin-error mitigation for optimisation) error-mitigated quantum annealing achieved substantially shorter time-to solution than standard D-Wave QA, D-Wave BQM, simulated annealing and Tabu search baselines. The error-mitigated quantum annealing approach presented in this article potentially elevates the efficiency and application scope of quantum annealing and would be applicable in solving other discrete optimisation problems that can be formulated as QUBO or Ising instances. The promising solution time advantage would be particularly impactful for time-critical optimisation applications.

Jim Cramer Was Happy The Market “Cared” About D-Wave Quantum – But Not How You Think Ramish Cheema Sat, August 15, 2026 at 5:28 PM EDT 3 min read QBTS +1.29% SMR -4.67% D-Wave Quantum Inc. (NYSE:QBTS)'s shares are up by 24% over the past year and are down by just as much year-to-date. Cramer hasn't held back discussing the firm and in most appearances, he has stressed the need to evaluate the firm's business. As D-Wave Quantum Inc. (NYSE:QBTS) reported its second quarter earnings on August 6th, the firm's shares closed the day 9% lower. Cramer discussed the move and wondered whether the market was becoming realistic about D-Wave Quantum Inc. (NYSE:QBTS): "What's incredible is that we never cared about earnings before, for this, for NuScale. And suddenly we care, I don't get it. I just think again, once again, there's kind of a realism sinking in. Let's, a lot of these guys have had such big moves. They're not based on anything. Or, let's just take some profits. I think the Situational mindset is going to be with us for a long time. Jim Cramer Tells Caller Down 15% on Netflix to Average Down While the shares closed lower, D-Wave Quantum Inc. (NYSE:QBTS)'s earnings came with several key figures that support the bullish argument. Arguably, the strongest of these was the firm's first half of 2026 bookings. These surged by 1,120% to $35.5 million. The bookings surge came due to purchase and enterprise agreements with Florida University and a Fortune 100 company. Additionally, 62% of D-Wave Quantum Inc. (NYSE:QBTS)'s second quarter revenue of $3.1 million was accounted for by commercial customers. Both these factors, along with a 668% jump in remaining performance obligations (RPOs), created solid avenues for tailwinds should the firm demonstrate sustained performance in the future. Yet, on the flip side, D-Wave Quantum Inc. (NYSE:QBTS)'s second quarter revenue dipped by 0.6% annually and came after its Q1 revenue had dropped by 81% to $2.
