The quantum router can speed up quantum computers

Quantum computers may be able to operate useful algorithms more quickly, thanks to the new quantum router that helps the data access to the right place faster.

Traditional computers avoid becoming slow when facing a partially complicated program using RAM (RAM) to temporarily store information. The component key to build a ram’s amount, Qram, is a router. This is not a router that directs your internet queens to the correct IP address, but rather an internal router that directs information traffic inside the computer.

Be Miao At Stanford University in California and its colleagues, it has now built such a device. “The motivation behind the project was one of the algorithms that used Qram. There were a lot of papers that came out mainly saying:” If we had Qram, we can do Xyz, “but this did not appear [experimentally]She says.

The new router consists of Qubits, and the basic building blocks for all quantum computers and quantum memories, made of super -delivered circuits to connect and control them with electromagnetic pulses. Similar to the traditional router, this quantity send quantum information to the quantum addresses. What distinguishes the device as the entire quantity is that it allows the address to encrypts not only in one place but in two overlays. This team tested three Qubits and found that the guidance had about 95 percent of sincerity.

This means that if it is combined into QRAM, the device can push the information to the state of quantity as it is impossible to say which of the two sites stored in them exactly – the exact type of phenomenon that is believed to make the quantum computers strong.

Linjin Duan At the University of Tsinghua in China, whose team previously built a quantitative router that was only operating during some runs, the new device is an important step towards building QRAMS practical, which may enable the operation of quantum machinery algorithms.

team member David Schuster At Stanford University, Stanford University says, there are still many open questions about the place where quantum guidance can make a practical difference, but the options are wide, from the well -known algorithms to research databases to creating quantum IP addresses for future Internet repetitions.

However, the current version of the router is still not reliable enough for some of these uses, so it must have less errors and contain more Qubits to move forward, he says Sébastien léger At Stanford University, who worked on the project.
