The cat qubit uses a quantum superposition of classical-like states of well-defined amplitude and phase to encode information.

The Startup Alice and Bob have been working on the cat qubit. Alice & Bob is a Paris-based quantum computing startup founded in 2020 by Théau Peronnin and Raphaël Lescanne, with a mission to build the ...

Alice&Bob, a Paris 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 work towards ...

What is a cat qubit? Quantum computers solve problems by exploiting the strange properties of matter and energy at very small scales, as described by the science of quantum physics.

The Ocelot logical qubit memory chip, shown schematically above, consists of five cat data qubits, each housing an oscillator that is used to store the quantum data.

Following quantum chip breakthroughs by Microsoft and Google, AWS scientists explain the role transistors play in this first-generation cat qubit architecture.

Called Ocelot, the new quantum computing chip is named after the spotted wild cat, while also giving a nod to internal "oscillator" technology that underlies the cat qubits.

Paris – March 11, 2025 – Fault-tolerant quantum computing company Alice & Bob today announced what they said is a significant advancement in cat qubit technology to reduce errors in quantum computers.

However, Bernien sees the great advantage of cat qubits in the fact that fewer physical cat qubits are required for an error-corrected, logical qubit than conventional qubits.
