Insider Brief Researchers demonstrated lattice surgery on superconducting qubits, enabling a fault-tolerant quantum operation between logical qubits while correcting errors during the operation. The experiment used surface-code error correction to split a single logical qubit […]
EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. “The concept of time has troubled philosophers and physicists for thousands […]
Insider Brief Los Alamos National Laboratory has established a new Center for Quantum Computing to consolidate its quantum research capabilities across national security, algorithms, computer science, and workforce development. The center will bring together up […]
The trajectory of a storm, the evolution of stock prices, the spread of disease — mathematicians can describe any phenomenon that changes in time or space using what are known as partial differential equations. But […]
Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new experiment shows how to perform quantum operations while continuously fixing errors, rather than pausing protection to compute. The team […]
Quantum 10, 1997 (2026). https://doi.org/10.22331/q-2026-02-06-1997 We describe an efficient, fully fault-tolerant implementation of Measurement-Based Quantum Computation (MBQC) in the 3D cluster state. The two key novelties are (i) the introduction of a lattice defect in […]
Quantum 10, 1996 (2026). https://doi.org/10.22331/q-2026-02-06-1996 This work shows that minimizing the depth of a quantum circuit composed of commuting operations reduces to a vertex coloring problem on an appropriately constructed graph, where gates correspond to […]
Insider Brief The QUICHE project is a newly funded UK–Germany collaboration aiming to integrate quantum computing workflows directly into the widely used ORCA quantum chemistry software. Backed by Innovate UK and Germany’s ZIM programme, the […]
Insider Brief Chinese researchers reported advances that move quantum communication closer to practical networks, combining longer-lived quantum memory with record-setting demonstrations of ultra-secure key distribution over fiber. The team generated device-independent quantum encryption keys over […]
Insider Brief Infleqtion, in collaboration with the University of Chicago and MIT, has advanced to Phase 3 of the Wellcome Leap Quantum for Bio (Q4Bio) Challenge to demonstrate quantum-enabled biomarker discovery for oncology. The team […]
