|---|---|---|
 | QuantumRegister()()() |
Default constructor, create a register of a single qubit
|
| QuantumRegister(Int32) |
Construct a quantum register with a specific number of qubits.
|
| QuantumRegister(array<Boolean>[]()[]) |
Create a new quantum register where each qubit is set to the bool specified in the array.
Qubit x will be set to element x in InitialQubitValues.
|
| ApplyOperation(IQuantumOperation) |
Apply a generic operation to the register.
|
 | ApplyOperation(ComplexMatrix) |
Apply a generic operation to the register.
|
| ApplyOperation(IQuantumOperation, array<Int32>[]()[]) |
Apply a generic operation to the specified qubits.
|
| ApplyOperationAll(IQubitOperation) |
Apply the single qubit operation to all qubits in the register.
|
| ApplyOperations(IEnumerable<(Of <(IQuantumOperation>)>)) |
Apply a series of operations to the quantum register. If any of the operations
are invalid and an exception is thrown then the state of the register is not altered.
|
| CloneForSlice()()() |
This copies over all the necessary members of the existing register into a new
one so that slice operations only have to worry about manipulating the exposed
qubits. Also makes the expansion of the QuantumRegister class easier since any
copying for slicing can be put here.
|
| CorrectOperationMatrix(ComplexMatrix) |
Correct an operation matrix so it takes into account the actual number of qubits in
the register.
|
| EliminateDuplicateReferences()()() |
It is possible to create a register with references to the same qubit. This
goes through and eliminates duplicate references, leaving the reference at
the lowest index.
|
| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| Finalize()()() | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
 | GetAppliedIndices(List<(Of <(Int32>)>)) |
Get how the exposed indices in the register match up to the target indices
in the operation. The result can be used in matrix expansion and reordering.
|
| GetCompleteRegister()()() |
Slices can be used to obtain subsets of a register. This method returns a register
that contains the whole set of qubits that have been included in this register. This
register will contain the qubits in their original order, regardless of slices.
|
| GetEnumerator()()() |
Enumerator to return a single qubit register for each qubit in
the register.
|
| GetHashCode()()() | Serves as a hash function for a particular type. GetHashCode()()() is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object.) |
| GetIncludedBinaryRepresentation(List<(Of <(Int32>)>), Int32) |
Get the binary representation of the exposed qubits that would be
operated on by an operation.
|
| GetIndexes(Int32, Int32) |
Get an array of indexes. This can be used when passing indexes
to methods that apply operations
|
| GetIndexes()()() |
Get an array of indexes. This can be used when passing indexes
to methods that apply operations
|
| GetLength()()() |
Get the length of the quantum register. Note that due to slicing
this length may be smaller than all the qubits actually contained in
the register.
|
| GetLocation()()() |
Returns the location of the quantum resource.
|
| GetNotIncludedBinaryRepresentation(Int32) |
Get the binrary representations of the indices that are not included
in Value.
|
| GetPlaceInMask(Int64, Int32) |
Get the place (0 based) in the mask that the current TestBit
is at. Example, if bit mask is 0x0A and test bit is 3 then
return 1. This is because 0x0A = 0000 1010 and bit 3 (0x08)
is set to true and is in place 1 (0 based).
|
| GetQuantumFourierTransformOperations()()() |
Get the operations that apply the Quantum Fourier Transform. These are then
applied in order for the normal QFT, or reversed and applied for the inverse
QFT. Thus the application of (inverse) QFT is merely the application of these
operations.
|
| GetState()()() |
Expose the state of the system. This is a deep copy of the state, so
there is no need to worry about inadvertently altering the state. This
is protected so user subclasses can access the state and internal so
that unit tests can access it.
|
| GetTotalLength()()() |
Slicing may result in a subset of the register being exposed. This gets the
total length of the register, which includes qubits that may be hidden
through slicing.
|
| GetType()()() | Gets the Type of the current instance. (Inherited from Object.) |

are in the bit mask are squezed into a value. Example if the bit mask is 1011
and the value is 1000 then it will return 0100. (because there is a gap in the bit
mask so it shifts it over one.
