New device for scaling up quantum computers
Australian scientists have developed a new cryogenic computer system called
Gooseberry which has potential for scaling up quantum computers from dozens to thousands of qubits.
Quantum computing – as opposed to traditional (or classical ) computing – has been around for many years now. This area of computer science involves the exploitation of physical phenomena such as superposition and entanglement to perform calculations. Unlike the bits of classical computers, which are based on binary ones and zeros, quantum computer qubits can work with multiple values simultaneously. By combining qubits in this way, it quickly becomes possible to work with exponentially larger numbers, with potentially revolutionary applications. If fully realised, quantum computers could solve problems in fields as diverse as cryptography, medicine, finance, artificial intelligence and logistics.
