Researchers from the University of Bristol have developed a new CMOS-compatible silicon photonics photon source that satisfies all the requirements necessary for large-scale photonic quantum computers. The research represents a significant step toward mass-manufacturable ideal
Physicists at Caltech have demonstrated the benefits of a lesser-studied approach for quantum computers that relies not on atoms but molecules. if a quantum computer platform uses qubits made of molecules, the researchers say, the
Xanadu, a leading company in photonic quantum computing, announced the release of the world’s first publicly available Photonic Quantum Cloud platform. Developers can now access Xanadu’s gate-based photonic quantum processors, in 8, 12, and soon
The Swiss company Zurich Instruments has just introduced its SHFQA Quantum Analyzer that operates at up to 8.5 GHz and can thus perform direct readout of superconducting and spin qubits. Conceived as the next generation
The Schwinger model (quantum electrodynamics in 1+1 dimensions) is a testbed for the study of quantum gauge field theories. Given an elementary or high-energy quantum field theory, the best demonstration of its efficacy is showing
Researchers at Google’s AI Quantum team have used a quantum computer to simulate a chemical reaction, the Hartree-Fock approximation of a real chemical system, for the first time. The reaction is a simple one, but this marks
Researchers at MIT, MIT Lincoln Laboratory, and Pacific Northwest National Laboratory (PNNL) have found that a qubit’s performance may soon hit a wall because of the low-level, otherwise harmless background radiation that is emitted by trace elements
For the first time, researchers from Duke University and the University of Maryland have designed a fully connected 32-qubit trapped-ion quantum computer register operating at cryogenic temperatures. The new system represents an important step toward
IBM on Thursday announced it’s reached a new quantum computing milestone, hitting its highest Quantum Volume to date. Using a 27-qubit client-deployed system, IBM achieved a Quantum Volume of 64. Quantum Volume is a metric
So far, superconducting quantum computers have certain constraints on qubit connectivity, such as nearest-neighbor couplings. To overcome this limitation, a team of researchers at RIKEN, Japan, has proposed a scalable architecture to simultaneously connect several
