Silicon vacancy centers in Silicon Carbide show promise as room-temperature qubits for quantum sensing applications, with researchers demonstrating that simultaneously operating both transitions in the spin-3/2 quartet through a novel duplex qubit scheme doubles the signal contrast and improves sensitivity compared to conventional single-qubit approaches.
QuTech researchers, collaborating with Fujitsu and Element Six, have achieved a significant quantum computing milestone by demonstrating diamond spin-based quantum gates with error rates below 0.1%—satisfying a critical threshold for quantum error correction and bringing us one step closer to scalable quantum computation.
Using Quobly’s Strategy to Build Qubits With FD-SOI Technology, Readout Architecture ‘Provides a Path to Low Power and Scalable Quantum’ ICs
Scientists have made a transformative discovery in quantum computing that challenges long-held assumptions about spin qubit assembly. The breakthrough research demonstrates that hydrogen bonds can effectively facilitate spin interactions between qubit components.
Engineers have substantially extended the time that their quantum computing processors can hold information by more than 100 times compared to previous results.
Researchers have engineered a record number of six, silicon-based, spin qubits in a fully interoperable array. Importantly, the qubits can be operated with a low error-rate that is achieved with a new chip design, an automated calibration procedure, and new methods for qubit initialization and readout.
A European consortium was launched today with the goal of scaling silicon quantum technologies. Named QLSI (Quantum Large-Scale Integration with Silicon), this four-year EU project, coordinated by CEA-Leti, will lay the foundation for the EU’s […]
