Noise cancellation by superposition of channels and superactivation of quantum capacity: Experimental realization by NMR
Deepika Bhargava, Arijit Chatterjee, Vishal Varma +1
Noisy quantum channels degrade quantum resources such as coherence and entanglement and hence pose challenges for realizing quantum technologies. Coherent control of noisy channels…
Efficient Many-Body Shadow Metrology via Clifford Lensing
Sooryansh Asthana, Conan Alexander, Anubhav Kumar Srivastava +2
Quantum probes that enable enhanced exploration and characterization of complex systems are central to modern science, spanning applications from biology to astrophysics and chemic…
Experimental prime factorization via the feedback quantum control
K. B. Hari Krishnan, Vishal Varma, T. S. Mahesh
Prime factorization on quantum processors is typically implemented either via circuit-based approaches such as Shor's algorithm or through Hamiltonian optimization methods based on…
Quantum Sensing via Large Spin-Clusters in Solid-State NMR: Optimal coherence order for practical sensing
Conan Alexander, T S Mahesh
Quantum entanglement has long been recognized as an important resource for quantum sensing. In this work, we demonstrate the use of multiple-quantum solid-state NMR for quantum sen…
Partial Quantum Shadow Tomography for Structured Operators and its Experimental Demonstration using NMR
Aniket Sengupta, Arijit Chatterjee, G. J. Sreejith +1
Quantum shadow tomography based on the classical shadow representation provides an efficient way to estimate properties of an unknown quantum state without performing a full quantu…
Direct Experimental Observation of Quantum Mpemba Effect without Bath Engineering
Arijit Chatterjee, Sakil Khan, Sachin Jain +1
The quantum Mpemba effect refers to the phenomenon of a quantum system in an initial state, far away from equilibrium, relaxing much faster than a state comparatively nearer to equ…
