9 quantum network component companies [list]

The supply chain for quantum networks is slowly emerging. Rapid advances are being made at all levels of the stack, converging towards the development of a practical quantum network. Because there are so many disparate components that make up the quantum network stack, it can be difficult to keep track of the relevant vendors for each component. Below, we list vendors in several categories of components that are crucial for the development of quantum networks.

While we hope it helps to give a picture of the space, this list is certainly not comprehensive. Please reach out to info@aliroquantum.com if we missed anyone.

Single- and entangled-photon sources

 

Qubitekk

Founded in 2013, Qubitekk offers several quantum network components. Their entangled photon source provides entangled photon pairs at 10,000 pairs/mW/s. In addition, Qubitekk also offers single-photon detectors as well as QKD systems. The QKD systems are offered both for demonstration purposes and for industrial control systems.

Qunnect

A spin-off from Stony Brook University, Qunnect is aiming to build a suite of quantum network components, including entangled photon sources. Qunnect's sources are engineered to interface with both optical fibers and atomic devices without the need for frequency conversion, a technically challenging step thus far.

NuCrypt

NuCrypt's technology spans fiber optics, nonlinear optics, electronic control systems, communication systems, optical measurement technology, and quantum optics. Their product line includes an entangled photon source that produces photons in the 1550 nm band.

Ki3 Photonics Technologies

Ki3 Photonics Technologies, develops low-footprint and power-efficient photonic systems for the generation of entangled photons over an optical frequency comb spanning the S, C, and L. Their solution is readily-implementable into existing telecom networks, paving the way for quantum networks with parallel/multi-channel information processing. 

Single-photon detectors

 

Quantum Opus

Superconducting nanowire single-photon detectors (SNSPD) have become the gold standard in single-photon detection. Quantum Opus, which is located in Novi, Michigan, develops a commercial SNSPD that offers an efficiency of >90%. Quantum Opus also offers a larger detector system, called Opus One.

Oxford Instruments

The Oxford Instruments iXon Ultra EMCCD imaging cameras provide single-photon detection efficiency of over 90%. In addition, the device is capable of detecting correlated photons. In contrast to the start-ups listed above, Oxford Instruments has been manufacturing tools for research since 1959.

Nu Quantum

A Cambridge spin-out, Nu Quantum specializes in single-photon devices, including both sources and detectors. Nu Quantum has provided components for a partnership with BT to develop a QKD solution in the U.K.

S Fifteen Instruments

Another academic spinoff,  S Fifteen specializes in photonic quantum technologies for secure communication. S Fifteen offers single-photon detectors that operate at both visible and infrared wavelengths. In addition, S Fifteen makes a suite of other photonics components, including a QKD system.

Transduction devices

 

QphoX


A new entrant to the quantum network component space, QphoX spun out of TU Delft just this year. QphoX is specifically focused on developing a quantum transduction devices, which they call their Quantum Modem. Their transducer will convert photons between the microwave domain and optical telecom frequencies. This is a key step to enable heterogeneous quantum network components to integrate with each other.

Miraex

Miraex offers photonics components for sensing, networking and computing. Their Quantum Transducer converts microwave wavelength photons to the optical domain at the single-photon level. Because quantum networks will need to interface with a variety of components, transducers will play a key role in enabling interoperability.

Quantum memories

 

Qunnect

In addition to their entangled photon sources above, Qunnect also develops quantum memories, a key component needed for practical entangled quantum networks. Notably, Qunnect's products all operate at room temperature, a potential strength for practical deployment in telecommunications infrastructure.
