QuasiQ

QuasiQ is a simple quantum computer simulator

Bell State Example

from quasiq import Circuit



# simplest quantum entanglement
# both qbits are maximally entangled
# so you wil either get |00⟩ or |11⟩ (but not |01⟩ or |10⟩)
 
circuit = Circuit(2)
circuit.h(0)
circuit.cx(0, 1)
circuit.print_circuit()

results = circuit.execute(shots=10,visualize=True)

for result in results:
    print(result)

Output:

                   
        m1     m2  
                   
       ┌───┐
