Core Idea

One-way quantum computer is treated here as the recurring computing and information systems identity summarized by this source-grounded definition: The one-way quantum computer, also known as measurement-based quantum computer (MBQC), is a method of quantum computing that first prepares an entangled resource state, usually a cluster state or graph state, then performs single qubit measurements on it. The one-way quantum computer, also known as measurement-based quantum computer (MBQC), is a method of quantum computing that first prepares an entangled resource state, usually a cluster state or graph state, then performs single qubit measurements on it.

Scope of Application

• Preparing the source state. Photons are the most common qubit system that is used in the context of one-way quantum computing.

• Preparing the source state. Furthermore, quantum emitters such as atoms or quantum dots can be used to create deterministic entanglement between photonic qubits.

• Correcting the output. Eventually, even though the outcome of a measurement is not deterministic in quantum mechanics, the results from measurements can be used in order to perform corrections, and carry on a deterministic.

• Equivalence between quantum circuit model and MBQC. The one-way quantum computer allows the implementation of a circuit of unitary transformations through the operations of entanglement and measurement.

• Hardware and applicationsTopological cluster state quan. Measurement-based computation on a periodic 3D lattice cluster state can be used to implement topological quantum error correction.

Clarity

A clear use of One-way quantum computer names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is The one-way quantum computer, also known as measurement-based quantum computer (MBQC), is a method of quantum computing that first prepares an entangled resource state, usually a cluster state or graph state, then performs single qubit measurements on it.

Manages Complexity

One-way quantum computer compresses multiple computing and information systems details into a stable diagnostic relation. The source shows both the central mechanism—the standard process of measurement-based quantum computing consists of three steps: entangle the qubits, measure the ancillae (auxiliary qubits) and correct the outputs.—and the practical consequence—the one-way quantum computer allows the implementation of a circuit of unitary transformations through the operations of entanglement and measurement.

Abstract Reasoning

1. Type the carrier. Identify the computing and information systems entities to which the claim applies.
2. State the relation. Use the source-grounded identity: The one-way quantum computer, also known as measurement-based quantum computer (MBQC), is a method of quantum computing that first prepares an entangled resource state, usually a cluster state or graph state, then performs single qubit measurements on it.
3. Check operation and conditions. Thereafter, the entanglement between two qubits can be performed by applying a (Controlled) CZ gate operation.
4. Demand recognition evidence.

Knowledge Transfer

Within the home domain. Knowledge about One-way quantum computer transfers literally when a new case preserves the same carrier type, relation, and recognition test. Photons are the most common qubit system that is used in the context of one-way quantum computing. Furthermore, quantum emitters such as atoms or quantum dots can be used to create deterministic entanglement between photonic qubits. Beyond the home domain. No canonical parent is asserted for One-way quantum computer.

Neighborhood in Abstraction Space

One-way quantum computer sits in a moderately populated region (55^th percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
