qstate: The qstate class
In qsimulatR: A Quantum Computer Simulator

This class represents a quantum state

The qubits are counted from 1 to nbits starting with the least significant bit.

nbits: The number of qubits
coefs: The 2^nbits complex valued vector of coefficients
basis: String or vector of strings. A single string will be interpreted as the collapse-parameter in genComputationalBasis. A vector of length 2^nbits yields the basis directly.
circuit: List containing the number of non-quantum bits ncbits and a list of gates gatelist applied to the original state. Filled automatically as gates are applied, required for plotting.
