dwaveNext four years will determine if noisy quantum computers can beat current computers

From November 2017 to March 2018 there was the announcement of IBM 50 qubit prototype, Intel’s 49 qubit test chip and Google 72 qubit processor. These processors had 10% to as low as 1% error rates. In 2017, D-Wave systems …

diamondDemo of two-qubit fault-tolerant universal holonomic quantum gates could enable faster quantum computers

Japases researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and fault-tolerant universal quantum computers. A quantum computer is a powerful machine with the potential to solve complex problems much …

physicsRigetti Computing hopes to have a functioning 128 qubit quantum computer within 12 months

Rigetti Computing has designed a microchip for quantum computers that would have more than six times as many qubits as Rigetti’s current 20 qubit machines. That would be more powerful than IBM’s 50-qubit computer and more powerful than Google’s 72-qubit …

quantum computersSuperconducting gatemon qubit could be the next quantum computing tech to scale to 50+ qubits

There have already been several quantum computer technologies that have scaled to 50-100 qubits. Gatemon superconducting qubits appear ready to scale to that level as well. Nature Nanotechnology – Superconducting gatemon qubit based on a proximitized two-dimensional electron gas Abstract …

photonic computersSingle photon quantum transistor could be the basis for future billion qubit quantum computers

Researchers have demonstrated the first single-photon transistor using a semiconductor chip. The device has numerous holes in it, making it appear much like a honeycomb. Light entering the chip bounces around and gets trapped by the hole pattern. A small …
