An international team have succeeded in transforming 20 entangled quantum bits into a state of superposition. This is an important step in the development of quantum computers after the old record of 14 qubits remained unchanged since 2011.
Researchers have developed an algorithm to simulate returning a particle briefly to the past. The results suggest new paths for exploring the backward flow of time in quantum systems.
IBM has announced that its System Q One quantum computer has doubled in performance in each of the past two years. IBM is one of the big-name companies working to create a truly useful quantum computer.
IBM unveiled the IBM Q System One, billed as the first-ever quantum computer designed for businesses to put to their own use – though the company is clear that this is only the first step towards a broader revolution.
IonQ was founded on a gamble that 'trapped ion quantum' computing could outperform the silicon-based quantum computers that Google and others are building. As of right now, it does.
A startup based in Maryland has released and tested an impressive new quantum computer that demonstrates the power of an occasionally overlooked quantum computing architecture.
Scientists have now demonstrated for the first time that quantum computers do indeed offer advantages - they developed a quantum circuit that can solve a problem that is unsolvable using any equivalent classical circuit.
Spanish researchers claim they have successfully mimicked Darwinian evolution using a quantum computer.
System lets researchers explore phase transitions in a quantum system.
A new quantum device entangles 20 quantum bits together at the same time, making it perhaps one of the most entangled, controllable devices yet.
Researchers from two teams now working with Intel have reported advances in a new quantum computing architecture, called spin qubits.
A team from Australia have found a "quantum hack" - a way to modify qubit surface codes, improving quantum error correction by up to four hundred per cent.
Australian and Dutch engineers created a complete design for a quantum computer chip that can be manufactured using mostly standard industry processes.
Physicists have invented a microcircuit based on topological insulators, a new phase of matter awarded the 2016 Nobel Prize in Physics.
Physicists have unveiled a programmable five-qubit processing module that can be connected together to form a powerful quantum computer.
