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 …

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 …

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 …

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 …

A 2048 qubit D-Wave 2000Q™ quantum computer was used to predict phase transitions within a particular quantum mechanical system known as the transverse field Ising model. This work has significantly raised the bar in regards to size and complexity of …

Arxiv – 18-qubit entanglement with photon’s three degrees of freedom They used * 30 single-photon interferometers in total. * The outputs are detected by 48 single-photon detectors Scheme and experimental setup for creating and verifying 18-qubit GHZ state consisting of …

Volkswagen experts will simulate the chemical structure of batteries on quantum computers. They have succeeded in simulating industrially relevant molecules using a quantum computer. This is important for the development of high-performance electric vehicle batteries. They simulated molecules like lithium-hydrogen …
