New Quantum Memory Reading Method Developed, Paving The Way To A Functional Quantum Computer

Back in 2012, a well-known physicist had an exciting idea, which was later pitched to Google. Seth Lloyd envisioned a quantum internet application which harnessed the power of quantum memory to answer a query instantly. The new type of memory would have been called QRAM and would have been a significant step towards a functional quantum computer.

While Google didn’t find the idea to be interesting, the concept of quantum memory is quite intriguing. The memory could become a great additional resource for future computers which will use quantum processors. Quantum CPUs are still in development, but the potential is enormous.

While classic computer systems use bits to perform certain operations, a quantum computer will employ quantum bits or qubits, to conduct the same actions at a superior speed that will overtake even the strongest supercomputers available today. IBM is already offering functional 20-qubit processors, but in the current stage, the technology cannot be exploited beyond experiments which take place in controlled conditions.

Quantum computer is one step closer as scientists developed a new quantum memory reading method

The main issue posed by the development of quantum memory is tied to the method used to access the information stored in qubits in a minimal amount of time and effectively limiting the number of errors that may appear.

Scientists can recover the target information by releasing a short microwave pulse aimed at a superconducting circuit which contains the qubit. The reflect microwave is then read and interpreted.

A researcher from the Aalto University has managed to create a new quantum memory reading method which allows the researcher to extract useful information at a superior speed. The team was able to finish an experimental readout in 300 nanoseconds, but they hope to reduce the timeframe to 100 nanoseconds or less.

The result marks a breakthrough which is already acknowledged by the scientific community with some researchers believing that it marks a significant step towards the development of a functional quantum computer shortly. The results have been published in a peer-reviewed journal, and the researchers are now working on refining the new quantum memory reading method.
