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…
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 Alternating Operator Ansatz for the Preparation and Detection of Long-Lived Singlet States in NMR
Pratham Hullamballi, Vishal Varma, T. S. Mahesh
Designing efficient and robust quantum control strategies is vital for developing quantum technologies. One recent strategy is the Quantum Alternating Operator Ansatz (QAOA) sequen…
Experimentally Extending Quantum Kernel Learning to Quantum Data by NMR
Vivek Sabarad, Vishal Varma, T. S. Mahesh
Quantum kernel learning (QKL) promises efficient machine learning by encoding feature maps onto exponentially large Hilbert spaces inherent in quantum systems. Using the liquid-sta…
