AWS's first-ever quantum chip uses "cat qubits" to reduce errors exponentially as more qubits are added to a system. Scientists say it will lead to scalable and efficient quantum computers.

What are cat qubits? Cat qubits are superconducting qubits inspired by the famous Schrodinger’s cat thought experiment, where the cat can exist in two states simultaneously- alive and dead.

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

“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 ...

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.

Cat qubits address the issue where traditional qubits, which can be in a state of 0, 1 or a “superposition” of both, are sensitive to their environment.

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.

In its present version, the Ocelot chip contains only five of the so-called cat qubits, not enough to perform actual logical operations but enough to store a quantum bit of information.

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.

Alice & Bob, a frontrunner in the race for fault-tolerant quantum computing, has announced a significant advancement in cat qubit technology to reduce errors in quantum computers. Cat qubits are a ...

Researchers at Amazon Web Services (AWS) have reported that they have succeeded in improving the efficiency of quantum computers by using 'cat-state qubits,' named after this phenomenon.
