func (qreg *QReg) BMeasurePreserve(index int) int

Measure a bit without collapsing its quantum state

func (*QReg) BProb

func (qreg *QReg) BProb(index int, value int) float64

Get the probability of observing a state for a specific bit

func (*QReg) BSet

func (qreg *QReg) BSet(index int, value int)

Set a particular bit in a QReg

func (*QReg) Copy

func (qreg *QReg) Copy() *QReg

Copy a quantum register

func (*QReg) Measure
