py2QAN 0.0.1

2QAN is an open source compiler for two-local qubit Hamiltonian simulation algorithms.

2QAN

2QAN is a quantum compiler for 2-local qubit Hamiltonian simulation algorithms. 2QAN uses algorithm-specific routing and scheduling techniques and can target different device topologies, different gate sets (e.g., CNOT/CX, SYC, iSWAP, sqrt_iSWAP, etc.).

A mapping algorithm based on quadratic assignment problem (QAP) is implemented in 2QAN for small benchmarks. The QAP mapper could find good qubit initial placements for small circuits, but becomes very slow for large circuits. For fast compilation, especially for circuits with more than 40 qubits, we encourage users to use other different qubit mapping techniques such as the ones in Qiskit and tket.

Requirements

1. 2QAN is using Qiskit (0.36.0) circuit representation
2. Other required python packages can be found in requirement.txt

Examples

TODO

1. 2QAN is using Qiskit (0.36.0) circuit representation, it's better to use IR .
2. Update tket and cirq versions, current examples with Pytket (0.11.0) and decomposition with cirq (0.11.1)
3. Improvement in routing algorithm
