To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Scientists encode these ...

In the strange world of quantum computing, randomness isn’t just noise. It’s a powerful resource. Whether you’re designing secure cryptographic systems, simulating processes that occur in nature, or ...

Using quantum states for processing information has the potential to swiftly address complex problems that are beyond the reach of classical computers. Over the past decades, tremendous progress has ...

A new record has been set for extremely precise control over qubits, the building blocks of quantum computers. This advance could lead to quantum computers that make fewer errors – if it can be ...

Quantum Art's new QPU could be both significantly smaller and also faster than competing quantum architectures. How can we reinvent quantum computing? Perhaps by shrinking it down and making it small: ...

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 ...

Chalmers engineers built a pulse-driven qubit amplifier that’s ten times more efficient, stays cool, and safeguards quantum states—key for bigger, better quantum machines. Researchers at Chalmers ...

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 ...

Today’s quantum computers are fundamentally impractical. But with a more resilient qubit, scientists believe they can unlock the technology’s extraordinary potential. Soon, they hope to prove it.

Quantum computers have great potential for meeting the challenges of the future. This includes, for example, the development of new materials with exactly defined properties. Quantum processors use ...

The odd phenomenon of quantum superposition has helped researchers break a fundamental quantum mechanical limit – and given quantum objects properties that make them useful for quantum computing for ...

Researchers have designed protein qubits that can be produced by cells naturally, opening possibilities for precision measurements of tissues, single cells, or even individual molecules. At first ...
