Exceptions and Errors raised by QNET

Summary¶

Exceptions:

`AlgebraError`	Base class for all algebraic errors
`AlgebraException`	Base class for all algebraic exceptions
`BadLiouvillianError`	Raised when a Liouvillian is not of standard Lindblad form.
`BasisNotSetError`	Raised if the basis or a Hilbert space dimension is unavailable
`CannotConvertToSLH`	Raised when a circuit algebra object cannot be converted to SLH
`CannotEliminateAutomatically`	Raised when attempted automatic adiabatic elimination fails.
`CannotSimplify`	Raised when a rule cannot further simplify an expression
`CannotSymbolicallyDiagonalize`	Matrix cannot be diagonalized analytically.
`CannotVisualize`	Raised when a circuit cannot be visually represented.
`IncompatibleBlockStructures`	Raised for invalid block-decomposition
`InfiniteSumError`	Raised when expanding a sum into an infinite number of terms
`NoConjugateMatrix`	Raised when entries of `Matrix` have no defined conjugate
`NonSquareMatrix`	Raised when a `Matrix` fails to be square
`OverlappingSpaces`	Raised when objects fail to be in separate Hilbert spaces.
`SpaceTooLargeError`	Raised when objects fail to be have overlapping Hilbert spaces.
`UnequalSpaces`	Raised when objects fail to be in the same Hilbert space.
`WrongCDimError`	Raised for mismatched channel number in circuit series

exception qnet.algebra.core.exceptions.InfiniteSumError[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraError

Raised when expanding a sum into an infinite number of terms

exception qnet.algebra.core.exceptions.CannotSimplify[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraException

Raised when a rule cannot further simplify an expression

exception qnet.algebra.core.exceptions.CannotConvertToSLH[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraException

Raised when a circuit algebra object cannot be converted to SLH

exception qnet.algebra.core.exceptions.CannotVisualize[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraException

Raised when a circuit cannot be visually represented.

exception qnet.algebra.core.exceptions.WrongCDimError[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraError

Raised for mismatched channel number in circuit series

exception qnet.algebra.core.exceptions.IncompatibleBlockStructures[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraError

Raised for invalid block-decomposition

This is raised when a circuit decomposition into a block-structure is requested that is icompatible with the actual block structure of the circuit expression.

exception qnet.algebra.core.exceptions.CannotEliminateAutomatically[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraError

Raised when attempted automatic adiabatic elimination fails.

exception qnet.algebra.core.exceptions.BasisNotSetError[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraError

Raised if the basis or a Hilbert space dimension is unavailable

exception qnet.algebra.core.exceptions.UnequalSpaces[source]¶

Bases: qnet.algebra.core.exceptions.AlgebraError

Raised when objects fail to be in the same Hilbert space.

This happens for example when trying to add two states from different Hilbert spaces.

exception qnet.algebra.core.exceptions.OverlappingSpaces[source]¶
