Dr. Fernando Quijandria, Staff Scientist (commencing Oct 2021)
I am a theoretical physicist working in the field of microwave quantum optics (superconducting circuits technologies) with focus on continuous-variable quantum information. I like to study novel phenomena both analytically and numerically but also, to model experiments in which these phenomena can be explored. My work involves the generation of nonclassical states of light [1,2], gate-based quantum computation  and more recently quantum error correction and quantum process tomography.

Dr. Sangkha Borah, Postdoctoral Scholar
I am an enthusiastic computational physicist who likes to use computers to make a physicist’s life easier. In this spirit, my research interests have evolved from molecular dynamics [1, 2], and density functional theory to applications based on machine learning techniques. Previous work of mine has focused on relaxation dynamics and hot carrier transport on 2D materials while developing an interest in machine learning as well. In the Quantum Machines Unit my main research interests will include the application of machine learning methods to quantum physical problems and to apply it to better design experiments, among others.

Ruvi Lecamwasam, Postdoctoral Scholar (commencing June 2021)
My work has been a mixture of optomechanics and quantum information theory, and how these relate to measurement. During my honours year I looked at how measurement itself could be used to create quantum states . For my PhD I worked as a theorist in an experimental group on a project to levitate a mirror using a laser beam, and so build a sensor that is completely isolated from environmental noise. The system could be solved using perturbation theory, allowing for an analytical treatment of the ‘optical spring’ the mirror oscillates on . I also investigated the idea of parameter estimation from an information theoretic point of view, and studied how the entropy of the prior information and your choice of measurement basis influence how you estimate the parameter.

Dr. Yanan Liu, Postdoctoral Scholar
My work has been about developing feedback control theory in stochastic quantum systems, including measurement-based feedback control and coherent feedback control. The main objectives of the measurement based stochastic techniques are to engineer the system towards a target quantum subspace or state, including entangled states and decoherence free subspaces. In the coherent feedback control technique we design coherent feedback controllers that achieve stable dynamics within a quantum system that is experiencing fault processes. Currently, I am studying how to enhance quantum squeezing within an Optical Parametric Oscillator (OPO) by designing a coherent feedback controller.

Dr. Kani Mohamed, Postdoctoral Scholar
I am a theoretical physicist working in the fields of quantum optics, optomechanics, and atomic physics. This includes understanding of the microscopic world as well as their interaction with external stimulus,and exploiting their quantum behaviour for precision metrology. My previous work in levitated optomechanics involves implementing phonon laser for force sensing below the thermal noise limit. I have also worked in Light-Matter interaction wherein I have used the quantum interference to manipulate the atomic coherence and control all nonlinear optical phenomena for realizing sensitive vector atomic magnetometer and atomic clock.

Dr. Isha Sanskriti, Postdoctoral Scholar
I am a material chemist with experience in synthesis, characterization and application of metal nanoparticles in the field of sensing [1, 2, 3]. The synthesized metal nanoparticles were exploited as a colorimetric sensor for environmentally/biologically relevant analytes viz., sulphide, cysteine, homocysteine and glutathione. I studied their sensing mechanism as well as various factors affecting shape, size and hence the optical properties of nanomaterials. During my studies, I was fascinated by the phenomenon of self-assembly  and its immense applications. In the Quantum Machines Unit I will work on developing novel types of quantum machines using chemical opto-mechanics.

Soma Mishra, PhD Student
Starting May 2020 I have joined OIST as a PhD student in Physics. I have a undergraduate degree of Master of Science (Honours) in Physics, from Birla Institute of Technology and Science (BITS) Pilani, Pilani, India, and completed a MSc in the Department of Physics, Indian Institute of Science (IISc.), Bangalore, titled 'Fabrication and low-temperature characterization of superconducting thin-film microwave resonators of Aluminum'. In that MSc I designed, fabricated and tested superconducting coplanar waveguide resonators in a cryogenic dilution fridge. Before starting my PhD I interned at OIST in the Light-Matter Interactions for Quantum Technologies Unit (Síle Nic Chormaic), and worked in the Nano-Bio-Optics lab and in fabrications. I am interested in quantum information technology, in quantum detectors of vacuum fluctuations, superconducting qubits and various kinds of artificial atomic systems. I am thrilled by quantum field theory and the rich potential of quantum electrodynamics.
