Among all the curious states of matter that can coexist in a quantum material, jostling for preeminence as temperature, electron density and other factors change, some scientists think a particularly weird juxtaposition exists at a
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
So far physicists have developed Quantum Key Distribution (QKD), in which photons are transmitted. The process allows two parties to share, without risk of interception, a secret key used to encrypt and decrypt information. But
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
Unitary designs play an important role in quantum information theory and beyond. Applications include the ubiquitous decoupling technique in quantum information theory, quantum encryption, randomized benchmarking and more. Researchers have studied a weaker form of approximate
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
BBVA is closely following through various lines of research aimed at exploring applications of quantum computing in the world of finance. As part of this work, and in collaboration with Spanish startup Multiverse, the joint research team
