This Quantum Computer Is 200-Time Faster Than Ever

Quantum computers are extremely powerful devices that can handle complex problems like predicting particle interactions in chemistry or making security codes that are hard to break. They are in no way something exists only in labs, as quantum computing is developing fast and may reach $495.3 million in 2023.

Recently, researchers at the UNSW have made a breakthrough with quantum computing. What they created was a computer that can process complicating problems at a speed 200-time faster than other devices.

The lead researcher of this study is Michelle Simmons. She and the team have made the world’s fastest two-qubit gate among phosphorus donor electrons in Silicon. This tiny logic gate is capable of completing the whole computer tasks in merely 0.8 seconds, 200 times faster than the usual spin-based two-qubit gates.

The gates they have built are the foundation of a quantum computer based on silicon.

The data units on quantum computing are called qubits. Unlike bits (a bit has single binary value, which is either 0 or 1), qubits can be more than one state simultaneously. Quantum mechanics allows quantum bits to be in a super coherent superposition of both levels/states.

In this particular research, the qubits are made from single phosphorus atoms suspended in silicon. The reason for this choice is that silicon has the smallest noise level known to scientists.
