Reduced State Stabilizer Rényi Entropy as a Probe of Quantum Phase Transitions in Frustrated J_1-J_2 Spin Models
George Biswas, Santanu Sarkar, Jun-Yi Wu +1
We investigate whether the second-order purity-corrected stabilizer Rényi entropy (SRE) of reduced two-qubit density matrices can serve as a reliable local indicator of quantum pha…
Reduced-State Stabilizer Rényi Entropy as a Probe of Quantum Criticality in the Transverse ANNNI Model and the Quantum Compass Model
Santanu Sarkar, George Biswas, Jun-Yi Wu +1
We investigate the effectiveness of the stabilizer Rényi entropy (SRE), a quantifier associated with non-stabilizer resources (quantum magic), as an indicator of quantum phase tra…
Magnetic Field Detection Using a Two-Qubit System Under Noisy Heisenberg Interaction
George Biswas, Sayan Sengupta, Anindya Biswas
We propose a method to design a magnetic field detector using a noisy two-qubit system. The system evolves under a noisy Heisenberg interaction Hamiltonian, and we investigate its…
On Classical Simulation of Quantum Circuits Composed of Clifford Gates
George Biswas
The Gottesman-Knill theorem asserts that quantum circuits composed solely of Clifford gates can be efficiently simulated classically. This theorem hinges on the fact that Clifford…
Scalability enhancement of quantum computing under limited connectivity through distributed quantum computing
Shao-Hua Hu, George Biswas, Jun-Yi Wu
We employ quantum-volume random-circuit sampling to benchmark the two-QPU entanglement-assisted distributed quantum computing (DQC) and compare it with single-QPU quantum computing…
Fidelity and Entanglement of Random Bipartite Pure States: Insights and Applications
George Biswas, Shao-Hua Hu, Jun-Yi Wu +2
We investigate the fidelity of Haar random bipartite pure states from a fixed reference quantum state and their bipartite entanglement. By plotting the fidelity and entanglement on…
