Personal profile

Biography

Chaitanya was born in a suburb of New Delhi, the vibrant capital of India. Chaitanya received his undergraduate degree in Physics (Hons.) from the University of Delhi and a M.Sci. degree from the Indian Institute of Technology Delhi. Chaitanya then moved to the UK to pursue a doctoral degree from Heriot-Watt University, Edinburgh. Chaitanya's doctoral work included theoretical investigations of quantum features in mesoscopic mechanical systems.  The emphasis of Chaitanya's doctoral study was to study genuine quantum effects manifested in coupled oscillators with infinite dimensional Hilbert spaces.
 
Splendid with the Scottish weather Chaitanya remained in  Scotland and in fact  inched further north of Edinburgh to take a postdoctoral position at the University of St Andrews. In St Andrews Chaitanya's research focused on theoretical investigations of quantum effects in systems driven away from equilibrium. Chaitanya worked on building analytical and numerical techniques  to describe wide class of physical systems which exhibit quantum behaviour under the combined action of coherent  driving and unavoidable coupling to the external environment.
 
Chaitanya joined the York Centre for Quantum Technologies in March 2015. Chaitanya’s current research interests include combining disparate quantum degrees of freedom to bring together  the best of both worlds.  In the emergent era of quantum control, quantum degrees of freedom of light and matter play an important role in describing collective many-body quantum phenomena. Chaitanya is broadly interested in exploring  hybrid open quantum systems as robust building blocks for future quantum technology. When Chaitanya is not in the quantum world he enjoys cooking, running for charities and vociferously debating social injustice.  

Research interests

Light-matter coupled quantum systems are now seen as novel playgrounds toward realizing various tasks of quantum computation and  quantum information processing and testing foundations of quantum physics. These hybrid systems promise to combine  disparate quantum degrees of freedom in constructing  scalable quantum  architectures. However, physical quantum systems invariably also couple to their external environment and hydrid quantum systems are no exception. It is commonly  argued that quantum correlated states, including entangled states, are  extremely sensitive to noise and dissipation. For example,  environment induced decoherence tends to reduce quantum-coherent superpositions to incoherent mixtures. Quantum state engineering strategies have therefore  taken a center stage  in salvaging quantum coherence in hybrid  quantum systems. Chaitanya's main reserach interest is to exploit these noisy hybrid quantum systems as next generation quantum devices.
