cirq.Duration

class cirq.Duration(*, picos: Union[int, float] = 0, nanos: Union[int, float] = 0)

A time delta that supports picosecond accuracy.

__init__(*, picos: Union[int, float] = 0, nanos: Union[int, float] = 0) → None

Initializes a Duration with a time specified in ns and/or ps.

If both picos and nanos are specified, their contributions are added.

Parameters:

• picos – A number of picoseconds to add to the time delta.
• nanos – A number of nanoseconds to add to the time delta.

Methods

total_nanos()	Returns the number of nanoseconds that the duration spans.
total_picos()	Returns the number of picoseconds that the duration spans.
