A technical paper titled “Measurement-induced entanglement and teleportation on a noisy quantum processor” was published by researchers at Google Quantum AI, Google Research, Stanford University, University of Texas at Austin, Cornell University, University of Massachusetts, University of Connecticut, Auburn University, University of Technology Sydney, University of California, and Columbia... » read more

Research Bits: May 30

Improving qubits Researchers from QuTech say they have improved the ‘Andreev spin qubit’ by taking the two most promising qubits — the spin qubits in semiconductors and transmon qubits in superconducting circuits — and finding a hybrid way that uses the best of both qubit types. “Spin qubits are small and compatible with current industrial technology, but they struggle with interact... » read more

Factoring 2048-bit RSA Integers in 177 Days with 13 436 Qubits and a Multimode Memory

Abstract: "We analyze the performance of a quantum computer architecture combining a small processor and a storage unit. By focusing on integer factorization, we show a reduction by several orders of magnitude of the number of processing qubits compared with a standard architecture using a planar grid of qubits with nearest-neighbor connectivity. This is achieved by taking advantage of a tem... » read more
