A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the ...

Scientists at the Institute of Science Tokyo have announced a breakthrough in quantum error correction that could bring a large-scale quantum computer closer to ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...

Nonetheless, these schemes are often not compatible with other quantum devices that store information in bosonic systems, such as photonic resonators. Researchers at NIST/University of Maryland ...

Quantum computers are computing systems that process information leveraging quantum mechanical effects. These computers rely on qubits (i.e., the quantum equivalent of bits), which can store ...

Google's quantum chip Willow is a step change in quantum computing (Photo illustration by VCG/VCG via Getty Images) The Willow team claim that it can perform a complex calculation in just five minutes ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...

Algorithms called phantom codes could help quantum computers run complex programs without errors, overcoming a big hurdle for making the technology more broadly useful. Many popular error-correcting ...
