Quantum computers, by definition, are machines that implement quantum computing. It is very difficult to build a quantum computer, but scientists have a spirit called Never Give up and have been working hard for the development of quantum computers.
The reason why quantum computers are difficult to develop is because super-positioning qubits are difficult to survive at room temperature. In general, the superpositioning quantum can only survive for a few seconds.
A few days ago, scientists at the Oxford University Laboratory had succeeded in allowing quantum systems to survive for a full 39 minutes, which is a remarkable advance for quantum computers.
Stephanie Simmons, a material scientist at the University of Oxford, said: “This lifespan is at least ten times longer than previous experiments. Healthy and long-lived qubits are very helpful in proving the possibilities of quantum computers.â€
However, they are not active and all qubits in the experiment are in the same quantum state. To perform the actual calculations, so that the quantum computer can really work, the qubits need to be in different quantum states.
It sounds complicated and difficult, yes, but the 39-minute survival of the qubits in the lab has been a huge step forward. The remaining problems will be solved by scientists.
