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 ...

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.

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 ...

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 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 ...

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.

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.
