quantum-computingLive quantum clock built from real QuTech Delft measurements — and the entangled GHZ code does worse than the simple phase probe
🔗 https://ingo6.github.io/quanten-uhr/ A small self-built dashboard that turns real chip measurements from QuTech Delft (Tuna-9/17, via Quantum Inspire) into three side-by-side clocks: Quantum-Time (bit): does the qubit keep its value? (bit-flip channel) - World clock (centre): the real reference both sides are measured against - Quantum-Qubit (phase): two separate real measurements — - a shallow phase probe (D=100) → ≈ +7 pp, helps - an entangled GHZ code (D=300) → ≈ −15 pp, below break-even (hurts) Multilingual (DE/EN/FR/ES, switch top-left), built screen-reader-friendly, with a live online / maintenance / offline badge. Refreshes every few minutes, fully token-free. 🔗 https://ingo6.github.io/quanten-uhr/ submitted by /u/Sufficient-Main-4101 [link] [comments]

quantum-computingIonQ vs. D-Wave Quantum: Which Quantum Computing Stock Is a Better Buy in 2026?
The quantum computing race is intensifying as companies transition from laboratory experiments to commercial applications. Choosing between IonQ (IONQ +1.87%) and D-Wave Quantum (QBTS +0.56%) requires you to decide which specialized hardware approach will win.IonQ focuses on trapped-ion technology to build scalable quantum systems for enterprise use. D-Wave specializes in quantum annealing, a different method optimized for solving complex business calculations. Both companies are high-risk investments that aim to revolutionize computing as we know it today.The case for IonQIonQ utilizes trapped-ion technology to develop quantum platforms for diverse fields like drug discovery and financial modeling. The company is a notable player among quantum computing stocks that focus on specialized hardware. It maintains commercial agreements with the likes of Amazon for its cloud-based offerings. Following its July 2026 acquisition of SkyWater Technology, the company now operates its own domestic foundry to serve a broader range of customers.In its 2025 fiscal year (FY), revenue reached $130.0 million, representing a year-over-year increase of 201.9%. The company reported a net loss of $510.4 million for the same period.
