System Uses QD Array to Tackle Scalability Issues in Quantum Computing

Facebook Twitter LinkedIn Email Comments
WAKO, Japan, Jan. 2, 2019 — A research team led by the RIKEN Center for Emergent Matter Science (CEMS) has constructed a hybrid device for quantum computing, made from two different types of qubits, each with distinct advantages. The new system can be quickly initialized and read out, while simultaneously maintaining high control fidelity. In 1998, Daniel Loss, one of the authors of the current study, proposed, along with David DiVincenzo of IBM, to build a quantum computer by using the spins of electrons embedded in a quantum dot. The first type of qubit used for the new system — a single-spin qubit called...Read full article
