Quantum memory with integrated error detection has a lifetime of over two seconds
As with classical computer memories, quantum memory devices can store data as quantum states. There are a number of challenges that need to be overcome before new quantum memory.
A team of researchers from the University of Washington developed a quantum memory capable of error detection. It's able to store a superposition for over 2 seconds.
If the results are replicated successfully, the memory could open the way to developing more powerful quantum computers.
Quantum networks are systems that can distribute entangled quantum bits, or qubits, to users who are in different geographic locations.
Quantum memory is a very powerful quantum computer that can catch and store quantum bits that are encoded in photons without measuring them.
Physics and engineers are researching different physical systems that could act as quantum memory for quantum computers, including diluting atomic gases.
Our quantum memories are switches that either transmit or reflect light depending on whether they're on or off, unlike normal modulators, which are switched on and off by a single electron.
The possibility of using the magnetic fields of individual nuclei as quantum memories with longer lifetimes was the first thing that was explored.
Levonian said that the study's first objective was to create a solid-state quantum memory that could operate at higher temperatures.
Researchers are looking at ways to transfer quantum information from electrons to nuclear spins, because of the sensitivity that reduces their coherence times.
The prediction using squeezed SiVs was confirmed by previous experiments. Levonian and his colleagues wanted to reproduce this effect in their SiV-based quantum memory.
The new quantum memory's ability to operate at 4 degrees kelvin instead of 0.1 degrees kelvin could have significant consequences for the future large-scale implementations.
Cryogenic refrigerators that can bring the temperature down to 4 kelvin are about 5 times cheaper and 10 times smaller than refrigerators that cool objects down to 0.1 kelvin, and can fit in a server rack.
