Common quantum logic gates by name (including abbreviation), circuit form(s) and the corresponding unitary matrices. In quantum computing and specifically the quantum circuit model of computation, a quantum logic gate (or simply quantum gate) is a basic quantum circuit operating on a small number of qubits.
Qiskit (Quantum Information Software Kit) is an open-source software development kit (SDK) for working with quantum Computers at the level of circuits, pulses, and algorithms. It provides tools for creating and manipulating quantum programs and running them on prototype quantum devices on IBM Quantum Platform or on simulators on a local computer.
A logical qubit specifies how a single qubit should behave in a quantum algorithm, subject to quantum logic operations which can be built out of quantum logic gates. However, issues in current technologies preclude single two-state quantum systems , which can be used as physical qubits, from reliably encoding and retaining this information for ...
from ket import * a, b = quant (2) # Allocate two quantum bits H (a) # Put qubit `a` in a superposition cnot (a, b) # Entangle the two qubits in the Bell state m_a = measure (a) # Measure qubit `a`, collapsing qubit `b` as well m_b = measure (b) # Measure qubit `b` # Assert that the measurement of both qubits will always be equal assert m_a ...
As of December 2023, the concept has been used to demonstrate a 48 logical qubit processor. [6] [7] To perform computation, the atoms are first trapped in a magneto-optical trap. [6] Qubits are then encoded in the energy levels of the atoms. Initialization and operation of the computer is performed via the application of lasers on the qubits. [8]
The service was launched in May 2016 as the IBM Quantum Experience [1] with a five-qubit quantum processor and matching simulator connected in a star shaped pattern. At this time, users could only interact with the hardware through the quantum composer GUI. Quantum circuits were also limited to the specific two-qubit gates available on the ...
Arbitrary single-qubit phase shift gates () are natively available for transmon quantum processors through timing of microwave control pulses. [13] It can be explained in terms of change of frame. [14] [15] As with any single qubit gate one can build a controlled version of the phase shift gate.
Monroe's quantum computing research began as a Staff Researcher at the National Institute of Standards and Technology (NIST) with Nobel-laureate physicist David Wineland [4] where he led a team using trapped ions to produce the first controllable qubits and the first controllable quantum logic gate, [5] culminating in a proposed architecture ...
