Overhaul of the
inquanto.computables
moduleComputables no longer have responsibility for building or running circuits. They contain ingredients for computing an observable, and relations to other computables in an expression tree. Many have been renamed, and are now categorised into three submodules (* marks a new computable, and [old name if applicable]):
inquanto.computables.primitive
(primitive objects for building computable expression trees):ComputableTuple
[Computables
]ComputableNDArray
[ComputableArray
]
inquanto.computables.atomic
(these interact directly with inquanto protocols):MetricTensorReal
[ComputableMetricTensorReal] (no longer multiplied by factor of 1/4)
inquanto.computables.composite
(these are composed of atomic computables, and always have “Computable” appended to the end of the name):RestrictedOneBodyRDMComputable
[ComputableRestrictedOneBodyRDM
]UnrestrictedOneBodyRDMComputable

The following computables are no longer available:
ExpectationValueDerivativeReal
OverlapSquaredKetDerivative
Overhaul of the
inquanto.protocols
module.Protocols now have complete responsibility for building and running observable measurement circuits. They’ve also been renamed and refactored to be simpler to use. Many are pickle-able for easy pause-resume of experiments.
New protocol names [old name]:

The following protocols are no longer available:
ProtocolMidMeasurementGradient
ProtocolVacuumPhaseShift
inquanto.protocols.supporters
submodule is no longer available.Error mitigation is performed using Qermit or with new noise mitigation classes (available from the
inquanto.protocols
module):
Changes to the
inquanto.ansatzes
moduleRenaming of some ansatzes [old name]:

RealBasisRotationAnsatz
is replaced by three new classes, which have improved circuit depths:
QubitState
/FermionState
have been restructured to make their usage more consistent withQubitOperator
