The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, quantum computers should be able to—in theory—surpass the computational potential ...

A cryostat from a quantum computer stands during a press tour of the Leibniz Computing Center in 2022. Qubit is a key term in one of the most buzzy areas of technology: quantum computing. Qubits are ...

The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the implementation of quantum logic gates. These are essentially operations that ...

Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and DOE's Pacific Northwest National Laboratory (PNNL) have uncovered an unexpected interface layer that may be ...

Qubits, or quantum bits, are the fundamental units of information in quantum computing. Unlike classical bits, which can only exist in one of two states (0 or 1), qubits can exist in multiple states ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

Everyone in quantum computing agrees that error correction will be the key to doing a broad range of useful calculations. But early every company in the field seems ...

In its second antimatter breakthrough this month, CERN announced it successfully created the first-ever antimatter qubit, paving the way to even weirder quantum experiments. Reading time 3 minutes ...

Today, a startup called Atom Computing announced that it has been doing internal testing of a 1,180 qubit quantum computer and will be making it available to customers next year. The system represents ...

Microsoft's Majorana 2 in 2026 is 1,000 times more reliable than its predecessor, thanks to AI. Here is why the 2029 goal for quantum computers is now reachable.
