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

0
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

0
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 …
