Like its doomed namesake, the cat qubit exists in a double superposition of two quantum states simultaneously. More conventional qubits exist in a single superposition, existing as both 0 and 1.

Qedma specializes in error mitigation software. Its main piece of software, QESEM, analyzes noise patterns to suppress some ...

In 2024, a team at Google Quantum AI showed that this approach is scalable in a system of a few dozen qubits. However, a truly powerful quantum computer would require around a million data qubits and ...

“Cat qubits use the quantum superposition of classical-like states of well-defined amplitude and phase to encode a qubit’s worth of information,” they wrote. “A major advantage of cat qubits is their ...

Where traditional methods might need 20 million physical qubits, Alice & Bob estimates a few hundred thousand cat qubits could suffice. This reduction translates to lower costs, smaller hardware ...

These cat qubits are miniscule hollow structures of tantalum containing microwave radiation. They're fitted onto a silicon chip, alongside other qubits made from superconducting material.

Alice & Bob, a Paris-based startup that is a pioneer in the area of cat qubit quantum architecture, has raised €100 million ($104 million).It plans to use this Series B to continue working ...

Cat qubits have a distinctive feature compared to other options: bit flips are improbable, and get even less probable as you pump more photons into the resonator.

Crucially, cat qubits are resistant to decoherence — interference from the external environment that causes qubits to lose their quantum properties and lose any useful information they carry.
