Scientists experimenting with new ways to manipulate quantum states so that they can be harnessed for computing, communication, and metrology, has found a novel way to characterise and estimate such states. This method of characterisation called Quantum State Interferography, can help make such manipulations simpler so that several crucial operations in quantum technologies become less cumbersome. Scientists from Raman Research Institute, an autonomous institute under the Department of Science & Technology, Govt. of India, have found a new way of inferring the state of a system (both two-dimensional qubits, the simplest quantum system as well as higher-dimensional “qubits”) from an […]
