The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today's ...

Sending quantum information through a chain of qubits, like energy through a Newton's cradle, could be the key to faster operations and take quantum computing to the next level.

Coinbase says that while the threat isn't imminent, quantum may one day be able to break Bitcoin's cryptography.

ORNL has integrated a 20-qubit commercially available quantum computer at its Translational Research Capability (TRC) ...

Quantum signals are extremely fragile and can be overwhelmed by the intense optical noise generated by conventional internet traffic, requiring costly dedicated infrastructure for quantum networks.

In daily life, physics is straightforward. A tennis ball is either sitting on a table or not. A light is either on or off.

The machine that could change the world will be housed in a room that looks like a data center crossed with an ice cream ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a ...

There are some obvious big picture issues that stand between us and useful quantum computing. Issues like whether we can make enough high-quality hardware qubits to connect into the error-corrected ...

In a laboratory in Broomfield, Colorado, 98 atoms are suspended in mid-air, held in place by electric fields and cooled to temperatures close to absolute zero. Each atom is far smaller than anything ...

To this day, we have yet to see a quantum computer conclusively perform a single useful task. Existing machines are simply too small and error-ridden to solve commercially relevant problems. That hasn ...

The biggest difference between these two is funding. IonQ has no core business to fund its operations; it must sign research contracts to do so. As of now, IonQ's quantum business isn't sustainable, ...
