Any quantum information system operates with entanglement as a resource, which should be deterministically generated by a joint measurement known as complete Bell state measurement (BSM). The determinism arises from a quantum nondemolition measurement of two coupled qubits with the help of readout ancilla, which inevitably requires extra physical qubits. We here demonstrate a deterministic and complete BSM with only a nitrogen atom in a nitrogen-vacancy (NV) center in diamond as a quantum…

Single-Shot Readout of a Single Nuclear Spin

Single-shot, projective measurement of a single nuclear spin in diamond is demonstrated using a quantum nondemolition measurement scheme, which allows real-time observation of an individual nuclear spin’s state in a room-temperature solid.

High-fidelity projective read-out of a solid-state spin quantum register

The preparation and measurement of a multi-spin quantum register in a low-temperature solid-state system is demonstrated by implementing resonant optical excitation techniques originally developed in atomic physics, and compatibility with qubit control is shown.

A nondestructive Bell-state measurement on two distant atomic qubits

One of the most fascinating aspects of quantum networks is their capability to distribute entanglement as a nonlocal communication resource1. In a first step, this requires network-ready devices that

Spins associated to single defects in solids provide promising qubits for quantum information processing and quantum networks. Recent experiments have demonstrated long coherence times, high-fidelity

Observation of entanglement between a single trapped atom and a single photon

The direct observation of entanglement between stationary and ‘flying’ qubits is accomplished without using cavity quantum electrodynamic techniques or prepared non-classical light sources and it is envisioned that this source of entangling may be used for a variety of quantum communication protocols and for seeding large-scale entangled states of trapped ion qubits for scalable quantum computing.

Complete Bell state measurement of diamond nuclear spins under a complete spatial symmetry at zero magnetic field

The symmetry of the space where a spin qubit resides plays an essential role in the manipulation of quantum entanglement, which governs the performance of quantum information systems. Application of

Demonstrating the viability of universal quantum computation using teleportation and single-qubit operations

It is shown that single quantum bit operations, Bell-basis measurements and certain entangled quantum states such as Greenberger–Horne–Zeilinger (GHZ) states are sufficient to construct a universal quantum computer.

Summary form only given. Photons are natural carriers of quantum information over long distances. Matter systems have good storage capabilities and processing qubits. However, it is challenging to

Unconditional quantum teleportation between distant solid-state quantum bits

Diamond spin qubits are established as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing through unconditional teleportation of arbitrary quantum states between diamondspin qubits separated by 3 meters.

It is demonstrated that joint initialization, projective readout and fast local and non-local gate operations can all be achieved in diamond spin systems, even under ambient conditions, paving the way to large-scale quantum computation.
