The Quantum Density Matrix and its many uses: From quantum structure to quantum chaos and noisy simulators
Apoorva D. Patel
The quantum density matrix generalises the classical concept of probability distribution to quantum theory. It gives the complete description of a quantum state as well as the obse…
Shot-frugal and Robust quantum kernel classifiers
Abhay Shastry, Abhijith Jayakumar, Apoorva Patel +1
Quantum kernel methods are a candidate for quantum speed-ups in supervised machine learning. The number of quantum measurements N required for a reasonable kernel estimate is a cri…
Grover's Algorithm in Natural Settings
Apoorva D. Patel
The execution of Grover's quantum search algorithm needs rather limited resources without much fine tuning. Consequently, the algorithm can be implemented in a variety of physical…
The Science and Legacy of Richard Phillips Feynman
Avinash Dhar, Apoorva D. Patel, Spenta R. Wadia
This year is the 100th birth anniversary of Richard Philips Feynman. This article commemorates his scientific contributions and lasting legacy.
Quantum Trajectory Distribution for Weak Measurement of a Superconducting Qubit: Experiment meets Theory
Parveen Kumar, Suman Kundu, Madhavi Chand +2
Quantum measurements are described as instantaneous projections in textbooks. They can be stretched out in time using weak measurements, whereby one can observe the evolution of a…
Quantum error correction using weak measurements
Parveen Kumar, Apoorva Patel
The standard quantum error correction protocols use projective measurements to extract the error syndromes from the encoded states. We consider the more general scenario of weak me…
