Researchers at Sandia National Laboratories propose a very large family of benchmarks for probing the performance of quantum computers. They call them Volumetric Benchmarks (VBs) because they generalize IBM’s benchmark for measuring Quantum Volume. The Quantum Volume
In 2003, with “Playing Pool with π“, G. Galperin invented an extraordinary method to learn the digits of π by counting the collisions of billiard balls. Adam R. Brown at Google has demonstrated an exact isomorphism between Galperin’s
Parametrized quantum optical circuits are a class of quantum circuits in which the carriers of quantum information are photons and the gates are optical transformations. Classically optimizing these circuits is challenging due to the infinite
Discretizing spacetime is often a natural step towards modelling physical systems. For quantum systems, if we also demand a strict bound on the speed of information propagation, we get Quantum Cellular Automata (QCAs). These originally
Creating perfect entanglement requires full control over all qubit-qubit interactions. Until now, this goal has been hindered by the presence of an always-on and fundamental parasitic interaction that disturbs entanglement. Now, researchers at Forschungszentrum Jülich
Toronto-based Quantum Computing startup Xanadu, in partnership with MaRS and Creative Destruction Lab (CDL), announced the launch of what it claims is Canada’s first quantum network. Canada Quantum Network (CQN) will launch three nodes, quantum
Researchers at Berkeley present a quantum eigenstate filtering algorithm that allows to efficiently prepare a target eigenstate of a given Hamiltonian to high precision under reasonable assumptions. They have applied this algorithm to the quantum
ETH Zurich in Switzerland intends to further expand its leading position in quantum research, and so it is planning a highly specialised physics laboratory building on the Hönggerberg campus. A generous donation from ETH alumnus
Moscow State University in Russia is developing a quantum computer on an optical chip and aims to achieve 50 qubits using French startup Quandela’s technology. The highly efficient photonic quantum bit sources support Russian quantum
QuTech (a collaboration between TU Delft and TNO), KPN, SURF and OPNT are launching a collaboration designed to make significant progress in building a first ever quantum network connecting the Randstad, i.e. one of the
