New Qubit Control Mechanism Improves Prospects Of Quantum Computing

Quantum Computing is a new emerging filed and a lot of research is being done in this area. In quantum computing, information is represented by microscopic units called qubits. Measuring the movement of qubits is the core of Quantum Computing. The issue here is that the act of monitoring qubits generally results in damage of information. But scientists at Yale University have successfully devised a new system which can observe the movement of qubits without information loss.
Michel Devoret, the Fredrick William Beinecke Professor of Applied Physics and the man behind the research believes that the results are far better than any thoeritical formula. Now, the qubits can assume any stage either “0” or “1” or both of them simultaneously. The new non-destructive measurement system observes, tracks and documents all the changes in the state of a qubit and reduces the information loss. It is also helpful in correcting random errors.

The system uses a feedback mechanism along with continuous measurement that helps to control the steady decay of information. The researchers were able to measure one qubit successfully. Now, they are working on developing ultra-fast digital electronics to control more than one qubit at once.
