The Top Funded Quantum Security Companies and Who’s Backing Them

With the speculation around Sandbox AQ, the spin-out announced out of Alphabet earlier this year, we decided to take the opportunity to list some of the top-funded quantum security companies, and who’s backing them.

This is a non-exhaustive list in alphabetical order.

If you’re looking for more detailed information, make sure you check out our quantum security market report and see what our data platform has to offer.

1. Arqit

ArQit provides SaaS Quantum encryption solutions. We understand that their source of entropy will eventually be from a satellite and symmetric key data will be stored in global data-centres. Their focus has been on building corporate partnerships with blue-chip clients.

Including its SPAC funding, the business was aiming to raise over $400 million of capital. We understand the business raised ~$96 million net of redemptions in the SPAC however. This brings its total funding to date to an estimated $120 million. The business is now publicly traded (market cap ~$1.7 billion as of 14th April 2022) which it achieved via a SPAC in 2021.

Arqit was founded in 2016 and is headquartered in London, UK.

2. IDQuantique

ID Quantique provides provides quantum-safe network encryption, secure quantum key generation and quantum key distribution solutions and services to the financial industry, enterprises and government organisations globally. IDQ also commercializes a quantum random number generator used in the security, simulation and gaming industries. Their focus is on quantum encryption, though they are monitoring PQC

The business has raised over $70 million of financing. After venture investment from PhysTech Ventures, the business received a $65 million strategic investment from SK Telecom.

IDQuantique was founded in 2001 and is headquartered in Geneva, Switzerland.

3. ISARA

ISARA provides crypto-agile technologies and quantum-safe cryptography and aims to provide a practical and cost-effective transition to new cryptographic standards. In PQC the business provides a library of quantum safe algorithms. The business increasingly is focusing on its cryptoagility suite which allows it to offer a product irrespective of quantum requirements. We understand the business has seen management changes in the C-Suite over the last few months.

The business has raised ~$27 million of capital including grants and its backers include Quantum Valley Investments and Shasta Ventures.
