Dumb question…, page-17

I know the focus at Archer is to get a qubit that works sufficiently well at “room temperature”. Currently they have told us the coherence time is about 230 nanoseconds?I don’t know if that is sufficient for the “room temperature” goal or if they need longer.Would any of the tech gurus care to guess?

A coherence time of 230 nanoseconds is not sufficient for room-temperature qubits. In order to be useful for quantum computing, qubits need to have coherence times of at least microseconds, and preferably milliseconds or even longer. There are a number of challenges that need to be overcome in order to achieve this, including finding materials with long coherence times at room temperature, and developing new methods of qubit control and readout.

However, there is a lot of research activity in this area, and there have been some recent advances. For example, a team of researchers at Google AI recently demonstrated a qubit with a coherence time of 90 microseconds at room temperature. This is a significant improvement over previous results, and it shows that it is possible to achieve the necessary coherence times for room-temperature qubits.

It is likely that further advances will be made in this area in the coming years, and that room-temperature qubits will become a reality. This would be a major breakthrough for quantum computing, as it would make it possible to build quantum computers that are much more powerful and scalable than current devices.

Here are some of the challenges that need to be overcome in order to achieve room-temperature qubits:Finding materials with long coherence times at room temperature.

Most materials lose their coherence at room temperature, due to the presence of thermal noise.

Researchers are looking for materials that have long coherence times even at high temperatures.Developing new methods of qubit control and readout.

Current methods of qubit control and readout are not efficient enough for room-temperature qubits. Researchers are developing new methods that are more efficient and less susceptible to noise.

Despite these challenges, there is a lot of optimism in the field of quantum computing. There has been a lot of progress in recent years, and it is likely that room-temperature qubits will become a reality in the coming years.
