Q-CTRL has expanded its U.S. presence with a new office in San Francisco to better access top talent, industry partnerships, and venture capital in Silicon Valley. The company aims to leverage the region’s deep technology […]
Quantum 9, 1631 (2025). https://doi.org/10.22331/q-2025-02-11-1631 Strongly-correlated quantum many-body systems are difficult to study and simulate classically. We recently proposed a variational quantum eigensolver (VQE) based on the multiscale entanglement renormalization ansatz (MERA) with tensors constrained […]
Quantum 9, 1630 (2025). https://doi.org/10.22331/q-2025-02-11-1630 Accurate simulations of vibrational molecular spectra are expensive on conventional computers. Compared to the electronic structure problem, the vibrational structure problem with quantum computers is less investigated. In this work […]
Quantum 9, 1629 (2025). https://doi.org/10.22331/q-2025-02-11-1629 Recent results in relativistic quantum information and quantum thermodynamics have independently shown that in the quantum regime, a system may fail to thermalise when subject to quantum-controlled application of the […]
Quantum 9, 1628 (2025). https://doi.org/10.22331/q-2025-02-11-1628 What does it mean for a causal structure to be `unknown’? Can we even talk about `repetitions’ of an experiment without prior knowledge of causal relations? And under what conditions […]
Insider Brief: Scaling superconducting quantum processors is a major challenge due to the complexity of cryogenic wiring and microwave components required for qubit control and readout. Researchers from QphoX, Rigetti Computing, and Qblox propose optical […]
Insider Brief Photonic Inc. has introduced a new class of Quantum Low Density Parity Check (QLDPC) codes, called SHYPS, which significantly reduces the number of qubits required for quantum computation and error correction, potentially accelerating […]
Memory and Circuit Simulations of a [[49,9,4]] SHYPS Code Photonic Inc. has announced a significant breakthrough in quantum computing with the introduction of a new error correction code set in the Quantum Low Density Parity […]
Insider Brief: SEALSQ invested in ColibriTD to integrate its quantum-as-a-service platform into SEALSQ’s Quantum Roadmap, advancing post-quantum security and quantum computing adoption. ColibriTD’s technology helps industries like aerospace, energy, and defense solve complex mathematical problems […]
Qubits—the fundamental units of quantum information—drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely on electrical signals and are difficult to scale. Click to […]
