# Top 5 Company Pioneering Quantum Cryptography & Encryption

The development of quantum information theory has accelerated the engineering and hardware of quantum computers. The Nobel Prize in Physics 2022 was given to three researchers who carried out "***ground-breaking experiments using entangled quantum states***", in which two particles act as a single unit even when they are separated. No matter how far away two entangled particles are from one another, what occurs to one influences the state of the other particle, according to studies done by ***Alain Aspect, John F. Clauser, and Anton Zeilinger.*** But this isn't just a matter of an honour being awarded or proving Einstein wrong. It is a milestone in Quantum Information Theory research been done for many decades. Finally, Hard work has started to pay off.

Quantum computers are here to stay and quantum networks, and secure quantum encrypted communication are now part of a major field of study. Most of the brilliant scientist are dedicated to inventing and offering quantum-safe encryption tools, SDKs, protocols that will never be vulnerable to decryption by quantum computers.

The commercial cryptography landscape is changing rapidly with the early PQC business already provides a wide range of solutions, including from software libraries to silicon IP and SoC design for semiconductors, as well as first applications in messaging, VPNs, key management, blockchain, and IoT.

*In this post, we will dive into the top 5 companies pioneering commercial QKD and QRNG solutions.*

**[ID Quantique:](https://www.idquantique.com)** Based in Geneva, Switzerland, Quantum Key Distribution (QKD) systems, quantum secure network encryption, single photon counters, and hardware random number generators are all offered by the firm. ID Quantique provides photon counting solutions for the visible and near infrared parts of the optical spectrum, as well as pulsed laser sources, counting and timing circuits, and photonic sensor systems. [Their products](https://www.idquantique.com/quantum-safe-security/products/) are focused on Quantum Key Distribution (QKD) solutions for corporate, government, and telecommunications stage of implementation.

Key achievements of the company includes the first-ever deployment of quantum key distribution in a live network environment, the first deployment of QKD over a multiplexed network for commercial clients, the longest-running quantum crypto installation (since 2007), and participation in the demonstration of the longest QKD distance to date, which was 421 kilometres.

**[QuintessenceLabs:](https://www.quintessencelabs.com)** The Australian-based cybersecurity firm QuintessenceLabs develops hardware random number generators, quantum key distribution (QKD) systems, and other encryption solutions with automatic key [zeroization](https://en.wikipedia.org/wiki/Zeroisation) in addition to [products ](https://www.quintessencelabs.com/products)for managing encryption keys and policies that comply to the Key Management Interoperability Protocol (KMIP).

A well-known algorithm used by business is called [one time pad](https://en.wikipedia.org/wiki/One-time_pad), and it has some very strong security features, the most significant of which is something called information theoretic security, which essentially means that there are no attacks that can be mounted algorithmically or through computational power that can crack it. It performs as well as the key itself

Recently team of researchers who created a quantum logic gate in silicon, allowing computations between two qubits of information. They are one of the big players racing to build the world's first quantum computer in silicon.

**[MagiQ Technologies:](https://www.magiqtech.com)** US-based technological development firm best recognised for the commercial availability of quantum key distribution systems. MagiQ Tech now serves commercial and government clients with solutions in the test and measurement, optical sensing, and communications areas. DARPA, the US Navy, NASA, and the US Department of Energy are among its federal clients.

[MagiQ QPN](https://www.magiqtech.com/solutions/network-security/) implements the[ BB84 protocol, which was created in 1984 by Bennet and Brassard](https://en.wikipedia.org/wiki/BB84). This protocol assumes that the receiver and sender share an optical link (fibre) as well as a traditional (non-quantum) unencrypted communication channel, such as a normal internet connection.

**[Crypta Labs:](https://cryptalabs.com)** A UK-based company develops, validates, and manufactures trusted quantum enhanced technology [products](https://cryptalabs.com/quantum-random-number-generator/). Their main offering is a data center-specific, 1U rack mountable quantum random number generator device.

The first breakthrough, for which they have a patent, was the notion of utilising a diffuser to scatter photons, which would then be caught using a camera to harness the entropy. Due to the difficulty of integrating and miniaturising such a system, the team continued its research into alternative sources of entropy. With the creation of the discrete QOM in 2021, a significant advance was accomplished.

They take Quantum as Service approach, especially for blockchain businesses, where decentralized solutions make quantum security difficult, this is of particular interest. Despite the fact that they propose a decentralised approach, it is becoming increasingly obvious that there will be parts of the Web3 space where this happens.

**[NuCrypt:](http://nucrypt.net/index.html)** The US-based company creates [devices](http://nucrypt.net/index.html) that combine photonic, electrical, and quantum technology. The major objective of the firm is to deliver photonic instruments to the research and development community in order to boost end user productivity. They offer the only full range of quantum optical gear capable of producing, distributing, and measuring entangled photons.

NuCrypt owns a substantial amount of intellectual property relating to the design and implementation of photonic/electronic systems. Such as Noise-Based Encryption, Single Photon Detection (SPD) Technology, Entangled Photon Generation and Measurement which is very excited and pantented solutions for the market.

There are many more companies to follow up [CryptoNext, Kets, Qrypt, Post Quantum, Quantum Resistant Ledger, Single Quantum.](https://www.ventureradar.com/keyword/Quantum%20cryptography)

If quantum computing is ever going to be a threat to encryption, it is already one. In response to the coming quantum threat to encryption, your bussines must take significant steps. The most basic is that everything must be moved to quantum-safe standards in the next years before very powerful quantum computers are available. The most essential move, however, is to instantly put your sensitive data into a quantum-secure format. Don't encrypt your personal information in a way that makes it vulnerable to quantum computers.

Hackers can now collect encrypted data, hold off on decrypting it until technology advances. They are obtaining medical records, DNA data, keys to cryptowallets, encrypted social security numbers, banking information, and business trade secrets. The most of this data will be useful in years to come.
