Delay#
- class qiskit.circuit.Delay(duration, unit='dt')[source]#
Bases:
InstructionDo nothing and just delay/wait/idle for a specified duration.
Create new delay 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 of this delay.
- 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)[source]#
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)[source]#
Set a classical equality condition on this instruction between the register or cbit
classicaland valueval.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
Nonethen the name stays the same.- রিটার্নস:
a copy of the current instruction, with the name updated if it was provided
- রিটার্ন টাইপ:
- 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:
- 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:
- 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:
