Microsoft's 20 years of research into Majorana fermions seeks to build advanced quantum computers through topological qubits. These qubits promise increased stability and less error correction. Majorana fermions exhibit unique properties, allowing particles and their antiparticles to coexist. Microsoft has developed a chip that efficiently measures these particles, improving the reliability and control of qubits. A new precise measurement technique allows detection of subtle differences in electron states, essential for quantum computing. The challenge remains the hidden nature of quantum information due to the properties of Majorana particles, necessitating innovative approaches to measurement.
Majorana's theory showed that mathematically it's possible to have a particle that is its own antiparticle. That means you can take two of these particles and you bring them together, and they could annihilate and there's nothing left.
Majorana allows us to create a topological qubit, where the qubit is reliable, small and controllable.
Our new measurement approach is so precise that it can detect the difference between one billion and one billion and one electrons in a superconducting wire.
The nature of the Majorana particles means they hide quantum information, making it more robust, but also harder to measure.
