The British Ministry of defence (MOD) has purchased a quantum computer. This makes the Department of defense the first government department to buy quantum computers, but as they become more practical, other departments may also buy them. The Department of defense will now work with Orca computing to find ways to make quantum computing part of its work. Cooperate with Orca computing, a British quantum computer developer, to explore the application of quantum technology in the field of national defense. Stephen, head of the defence science and Technology Laboratory of the British Ministry of defence? Stephen till called it a "milestone moment". It is understood that quantum computers can perform extremely complex calculations very quickly and can solve problems that ordinary computers cannot solve. Specifically, the Department of defense will work with Orca's pt-1 quantum computer. This device is one of the first quantum computers that can run at room temperature. Previously, quantum computers needed rooms below freezing point to keep quantum bits cool. The Ministry of Defense said that pt-1 would help it understand quantum computers faster. Richard Murray, CEO of Orca computing, said: "Our cooperation with the Ministry of defense has provided us with hands-on close interaction, working with real hardware, which will help us jointly discover new applications of this revolutionary new technology." The fact that the British government purchased this technology shows that quantum computing is still in its early stage of development. Having said that, Orca has built a device that does not require refrigeration, which indicates that some important progress is being made in this field. (Xinhua News Agency)
