New Study Can Help in Exploring Ways to Control Noise in Quantum Technology

New Delhi, 24 Nov (ONA) --- A new study conducted by Bengaluru-based scientists has thrown fresh light on how a charged particle in contact with an environment in the presence of a magnetic field behaves when it is subjected to ultra-cold temperatures.

Scientists involved in the study have said that the latest findings could deepen existing knowledge and explore ways to control noise in the domain of quantum technology, the Science and Technology Ministry said in a release today.

Quantum technology is too vulnerable to disturbances in the environment that corrupt the information stored in quantum computers, thus understanding the role of noise in quantum technology and finding ways to control it has long been a challenge for scientists.

The scientists found how noise in the quantum domain can affect a charged particle in a magnetic field and traced the role of quantum noise in the decay of correlations at ultra-cold temperatures.

The study makes predictions about the nature of decay of factors called the position correlation function, the position-velocity correlation function, and the velocity autocorrelation function in the quantum domain accessible via ultra-cold atom experiments.

The predictions can be tested by considering a charged particle in a magnetic field at ultra-cold temperatures (of the order of a few nano Kelvin) in an optical molasses which mimics a viscous environment.
