Basic quantum circuit simulation with statevector and measurement.

from panta_sim import PantaSim, Circuit import numpy as np # Create a circuit with 2 qubits circuit = Circuit(2) circuit.h(0) circuit.cx(0, 1) circuit.measure_all() # Simulate sim = PantaSim() result = sim.run(circuit, shots=1000) print(result.get_counts())

Debug

Known issues

deprecatedThe `execute` function from panta_sim is deprecated in favor of `PantaSim.run` since v0.8.0.

fix

Use `sim = PantaSim(); result = sim.run(circuit, shots=... )` instead.

affects: >=0.8.0

breakingIn v0.8.0, the `Circuit` class moved from `panta_sim.circuit` to top-level `panta_sim`. Old imports will break.

fix

Change import to `from panta_sim import Circuit`.

affects: >=0.8.0

gotchaGPU backend requires CuPy and CUDA toolkit. Installation with `panta-sim[cuda]` does NOT install CUDA itself; you must have CUDA 11+ installed separately.

fix

Install CUDA toolkit from NVIDIA, then `pip install panta-sim[cuda]`.

affects: all

gotchaSimulation of circuits with >30 qubits may require significant memory (~16 GB for 30 qubits). The simulator does not warn before allocation.

fix

Monitor memory usage; consider using smaller circuits or GPU backend.

affects: all
