Cosmic tango between the very small and the very large: Addressing CMB anomalies through Loop Quantum Cosmology
Abhay Ashtekar, Brajesh Gupt, V. Sreenath
While the standard, six-parameter, spatially flat CDM model has been highly successful, certain anomalies in the cosmic microwave background bring out a tension between this mod…
Towards quantum simulation of spin systems using continuous variable quantum devices
Razieh Annabestani, Brajesh Gupt, Bhaskar Roy Bardhan
We study Bosonic representation of spin Ising model with the application of simulating two level systems using continuous variable quantum processors. We decompose the time evoluti…
Alleviating the Tension in the Cosmic Microwave Background using Planck-Scale Physics
Abhay Ashtekar, Brajesh Gupt, Donghui Jeong +1
Certain anomalies in the CMB bring out a tension between the six-parameter flat CDM model and the CMB data. We revisit the PLANCK analysis with loop quantum cosmology (LQC) pred…
A quantum hardware-induced graph kernel based on Gaussian Boson Sampling
Maria Schuld, Kamil Brádler, Robert Israel +2
A device called a 'Gaussian Boson Sampler' has initially been proposed as a near-term demonstration of classically intractable quantum computation. As recently shown, it can also b…
Classical benchmarking of Gaussian Boson Sampling on the Titan supercomputer
Brajesh Gupt, Juan Miguel Arrazola, Nicolás Quesada +1
Gaussian Boson Sampling is a model of photonic quantum computing where single-mode squeezed states are sent through linear-optical interferometers and measured using single-photon…
Photonic quantum algorithm for Monte Carlo integration
Patrick Rebentrost, Brajesh Gupt, Thomas R. Bromley
We present a continuous-variable photonic quantum algorithm for the Monte Carlo evaluation of multi-dimensional integrals. Our algorithm encodes n-dimensional integration into n+3…
