Assisted quantum simulation of open quantum systems

Enhanced quantum secret sharing protocol for anonymous secure communication utilizing W states

“…However, while classical ASS schemes have substantial practical value, they rely on the computational complexity of classical encryption, making them potentially vulnerable to adversaries with strong computational capabilities, especially the upcoming quantum computers and fast quantum algorithms. 12 , 13 Fortunately, QASS addresses this issue while ensuring information-theoretic security.…”

Quantum AI and hybrid simulators for a Universal Quantum Field Computation Model

“…A universal simulator requires an effective local Hamiltonian obeying the algebra of Pauli matrices, then encoded into qubits (quantum information, or QI) by a quantum circuit [54] . The reason is, Hamiltonian models of physical interest can be expressed in locally interacting spins, e.g., Ising and Heisenberg models [38 , 40 , 54] . The fidelity and probability for measuring spin type Hamiltonians, range from an open system exhibiting disorder in noisy channels, to models that use photons, sampled and slave particles [7 , 26 , 52] .…”

“…Examples for CFT are: A quantum double field (QDF) algorithm, called a QF lens coding algorithm (QF-LCA) [7] , [8] , [9] , [10] , [11] , [12] . A universal quantum algorithm (UQA) [38] listed for simulating open systems with expected success probability rates, when quantum-assisted on noisy intermediate-scale quantum (NISQ) devices [42] . From the four objectives, this qualifies as a QFCM, but not as a UQFCM.…”

“…This solution contributes to research method’s novelty in strong prediction and measurement fidelity estimates by a UQFCM. For example, to validate -data obtained on system’s classical and quantum states, a quantum-classical hybrid model is proposed to run on NISQ, or on quantum-assisted devices [7] , [8] , [9] , [10] , [11] , [12] , 18 , 38 , [42] , [43] , [44] , 53] , and photonic processors [52] . A quantum assisted algorithm [38] follows a UQA structure, and employs NISQ technology to reduce the quantum circuit depth and complexity when simulating open systems.…”
