Quantum computers are set to take a new turn inspired by Schrödinger’s Cat, one of the most famous thought experiments in physics. French technology company Alice & Bob has announced that it will develop an ambitious quantum computer based on this concept by 2030. The company’s new “cat qubit” technology is said to revolutionize quantum computing. Details in our news…
What is the “cat qubit” that inspired the future of quantum technology thanks to Schrödinger’s Cat and why is it important?
The Schrödinger’s Cat paradox assumes that a cat can be both dead and alive until the box is opened. Based on this idea, the “cat qubit” creates a quantum superposition that, unlike classical qubits, contains the dual state simultaneously. This approach is said to solve some of the fundamental problems faced by conventional quantum bits:
Error reduction: Cat qubits significantly reduce “bit-flip” errors (going from 0 to 1 or 1 to 0).
Resilience: They are more resistant to quantum distortions caused by environmental influences.
Alice & Bob has announced a five-stage plan to achieve a useful quantum computer. In the first phase, the company has successfully developed cat qubits. The next goals include the development of a logical qubit capable of error correction, the construction of a quantum logic gate and the creation of a processor consisting of 100 high-quality logical qubits.
Logical qubits are made up of groups of physical qubits and process information in a shared way to reduce error rates. This technology improves coherence in quantum systems, which have much higher error rates than bits in classical computers.
Clearly, Alice & Bob’s goals are ambitious, but the issues of commercial scalability and economic sustainability of quantum computers remain to be solved. Furthermore, unexpected technical or financial obstacles could delay the implementation of the plans. But if the company achieves its goals by 2030, quantum computers could revolutionize everything from molecular simulations to artificial intelligence.
