Reset

class qiskit.circuit.library.Reset

Bases: Instruction

Qubit reset.

Create new reset instruction.

Attributes

condition_bits

Get Clbits in condition.

decompositions

Get the decompositions of the instruction from the SessionEquivalenceLibrary.

definition

Return definition in terms of other basic gates.

duration

Get the duration.

label

Return instruction label

name

Return the name.

num_clbits

Return the number of clbits.

num_qubits

Return the number of qubits.

params

return instruction params.

unit

Get the time unit of duration.

Methods

add_decomposition(decomposition)

Add a decomposition of the instruction to the SessionEquivalenceLibrary.

assemble()

Assemble a QasmQobjInstruction

broadcast_arguments(qargs, cargs)

Validation of the arguments.

প্যারামিটার:

• qargs (List) -- List of quantum bit arguments.

• cargs (List) -- List of classical bit arguments.

Yields:

Tuple(List, List) -- A tuple with single arguments.

রেইজেস:

CircuitError -- If the input is not valid. For example, the number of arguments does not match the gate expectation.

c_if(classical, val)

Set a classical equality condition on this instruction between the register or cbit classical and value val.

নোট

This is a setter method, not an additive one. Calling this multiple times will silently override any previously set condition; it does not stack.

copy(name=None)

Copy of the instruction.

প্যারামিটার:

name (str) -- name to be given to the copied circuit, if None then the name stays the same.

রিটার্নস:

a copy of the current instruction, with the name updated if it was provided

রিটার্ন টাইপ:

qiskit.circuit.Instruction

inverse()

Invert this instruction.

If the instruction is composite (i.e. has a definition), then its definition will be recursively inverted.

Special instructions inheriting from Instruction can implement their own inverse (e.g. T and Tdg, Barrier, etc.)

রিটার্নস:

a fresh instruction for the inverse

রিটার্ন টাইপ:

qiskit.circuit.Instruction

রেইজেস:

CircuitError -- if the instruction is not composite and an inverse has not been implemented for it.

is_parameterized()

Return True .IFF. instruction is parameterized else False

qasm()

Return a default OpenQASM string for the instruction.

Derived instructions may override this to print in a different format (e.g. measure q[0] -> c[0];).

0.25.0 ভার্সন থেকে ডেপ্রিকেটেড: The method qiskit.circuit.instruction.Instruction.qasm() is deprecated as of qiskit-terra 0.25.0. It will be removed no earlier than 3 months after the release date. Correct exporting to OpenQASM 2 is the responsibility of a larger exporter; it cannot safely be done on an object-by-object basis without context. No replacement will be provided, because the premise is wrong.

repeat(n)

Creates an instruction with gate repeated n amount of times.

প্যারামিটার:

n (int) -- Number of times to repeat the instruction

রিটার্নস:

Containing the definition.

রিটার্ন টাইপ:

qiskit.circuit.Instruction

রেইজেস:

CircuitError -- If n < 1.

reverse_ops()

For a composite instruction, reverse the order of sub-instructions.

This is done by recursively reversing all sub-instructions. It does not invert any gate.

রিটার্নস:

a new instruction with

sub-instructions reversed.

রিটার্ন টাইপ:

qiskit.circuit.Instruction

soft_compare(other)

Soft comparison between gates. Their names, number of qubits, and classical bit numbers must match. The number of parameters must match. Each parameter is compared. If one is a ParameterExpression then it is not taken into account.

প্যারামিটার:

other (instruction) -- other instruction.

রিটার্নস:

are self and other equal up to parameter expressions.

রিটার্ন টাইপ:

bool

validate_parameter(parameter)

Instruction parameters has no validation or normalization.
