A rudimentary quantum debit card that can be loaded with unforgeable quantum money has been made from extremely cold atoms and particles of light. In this protocol, a bank issues banknotes made of ...

For all the hype surrounding quantum computers, the technology can sometimes appear to be a solution in search of a problem. Scientifically impressive, but not yet obviously useful in the real world.

Commercially viable quantum computing is still years away. Quantum computing is a major emerging technology that could be commercially viable by 2030. With that timeframe not all that far away, ...

Quantum squeezing is the generation of a quantum mechanical state whose uncertainty is less than the zero-point fluctuation. Precision measurement of an object with a quantum mechanical limit is vital ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem and opening paths to quantum teleportation and advanced quantum ...

IonQ and D-Wave Quantum have exciting technologies. Alphabet and Microsoft need to develop their own quantum computing capabilities in-house to improve profitability. The quantum computing arms race ...

Shares in the four largest publicly traded quantum computing companies (which I’ll refer to as the “Quantum Four” for short) are currently having a good 24 hours. Yesterday, the stock prices of D-Wave ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

Satellite GPS is a vital navigation technology designed for modern transportation including planes, ships, cars and smartphones. Everything works well unless GPS signals are jammed, spoofed or simply ...

Quantum stocks boomed on Wednesday, driven higher by acquisitions, analyst coverage and investor optimism. After the closing bell, a major government partnership was announced, sending the hot sector ...
