Quantum Algorithms for State Preparation and Data Classification based on Stabilizer Codes
Pejman Jouzdani, H. Arslan Hashim, Eduardo R. Mucciolo
Quantum error correction (QEC) is a way to protect quantum information against noise. It consists of encoding input information into entangled quantum states known as the code spac…
An Alternative Approach to Quantum Imaginary Time Evolution
Pejman Jouzdani, Calvin W. Johnson, Eduardo R. Mucciolo +1
There is increasing interest in quantum algorithms that are based on the imaginary-time evolution (ITE), a successful classical numerical approach to obtain ground states. However,…
Hybrid Quantum-Classical Eigensolver Without Variation or Parametric Gates
Pejman Jouzdani, Stefan Bringuier
The use of near-term quantum devices that lack quantum error correction, for addressing quantum chemistry and physics problems, requires hybrid quantum-classical algorithms and tec…
A Method of Determining Excited-States for Quantum Computation
P. Jouzdani, S. Bringuier, M. Kostuk
A method is presented in which the ground-state subspace is projected out of a Hamiltonian representation. As a result of this projection, an effective Hamiltonian is constructed w…
Symmetry Protected Topological Order by Folding a One-Dimensional Spin- Chain
Pejman Jouzdani
We present a toy model with a Hamiltonian on a folded one-dimensional spin chain. The non-trivial ground states of are separated by a gap from the excited s…
Numerical evaluation of the fidelity error threshold for the surface code
Pejman Jouzdani, Eduardo R. Mucciolo
We study how the resilience of the surface code is affected by the coupling to a non-Markovian environment at zero temperature. The qubits in the surface code experience an effecti…
Fidelity Threshold of the Surface Code Beyond Single-Qubit Error Models
Pejman Jouzdani, E. Novais, I. S. Tupitsyn +1
The surface code is one the most promising alternatives for implementing fault-tolerant, large-scale quantum information processing. Its high threshold for single-qubit errors unde…
