AQT Reports Quantum Volume of 32768 on LYNX System
Insider Brief AQT announced that its LYNX quantum computer achieved a Quantum Volume of 32768, the highest reported benchmark in Europe. The trapped-ion system improves on AQT’s earlier IBEX architecture with enhanced gate implementation and all-to-all qubit connectivity. The benchmark reflects improvements in qubit quality, connectivity, and circuit execution performance on commercially available hardware. PRESS RELEASE — The Quantum Volume (QV) test is an internationally applied benchmark originally proposed by IBM. The benchmark rigorously assesses and describes the computational power of a quantum computer with a single number. The QV metric describes how many “good” qubits a quantum information processor contains. In the procedure, random quantum circuits (according to the QV test protocol) are executed on an increasing number of qubits until the result is close to the ideally expected outcome. If the success probability of at least 100 different random circuits exceeds a certain threshold, the QV test is passed. Since the circuit size increases with the qubit number, the quality of the quantum operations also needs to increase in order to successfully pass the test. Hence, the higher the QV benchmark value, the more powerful the computer. The number is sensitive to many important aspects of a quantum computer, such as the number of qubits, the connectivity of the qubits, the quality of the quantum state preparation and measurement operations and the quality of the quantum gates. Because the Quantum Volume Test is agnostic of the underlying hardware and it tests hardware capabilities that is required for the successful implementation of a large class of quantum circuits, it can provide a strong statement about the computational power of any quantum information processor. AQT’s Next Generation Quantum Computer LYNX The AQT LYNX system is a new prototype of AQT’s quantum computers and it is an evolution of the successful AQT IBEX series. Building on sev
