Hi!
If you wouldn’t mind marking which of these are startups, that would be amazing. I have been researching them online and for some of them it is hard to distinguish which ones are backed startups vs. private companies.
All the companies on this list are Private, so their exact capital structure is not public information. However, I do not believe that any of the companies on this list are profitable enough to be self-funded. All of these companies have either received funding from a venture capital firm and/or a corporate investor or they are looking to get funding from an investment source. We do list the venture investors and their portfolio companies on the Venture Capital page when and if the investments are announced.
The one company that some might not call a startup is D-Wave since they were founded in 1999. Most of the rest were founded within the last few years.

ID Quantique acquired by SK Telecom…
If you read our news article dated February 28, 2018 on the $65 million investment in ID Quantique by SK Telecom, it indicates that SK has a large ownership position in ID Quantique, but it is not 100%. There are still other entities that own portions of the company. As a result, we will continue to list ID Quantique on this Private/Startup page since it is not a 100% owned subsidiary.

very informative ,it was…….. but i have a little suggestion that you could have sorted the startup country wise which would avoid scrolling down the whole page to find a single company …….
Thank-you for your comment. There is a quick and easy way to search a page to find a single company by using the built-in FIND function in your browser. In Chrome, for example, you type CTRL-F and a search box appears. Also note that this web site has a built-in SEARCH function that you can find in the lower left corner of each web page. You can type in a term and it will show you where it found that term anywhere on the web site.

Hi,
The second office of 1QBit is currently in Waterloo, not Toronto. There’s a confirmation for instance in the job page of our website, where you can select offers among the two offices (https://1qbit.com/careers/current-openings/)
Thank-you for spotting this. We have made the correction for your second office on this page.

Could you please add my startup to “Private/Startup Companies” in your site? Thanks very much in advance.
The startup is “QURECA, QUantum REsources & CAreers”,
and the description is
“At QURECA we are creating global opportunities with Quantum Technologies.
We provide professional services and all resources needed for businesses and institutions to be ready, make a difference, and create value.
We provide the link between the stakeholders in the quantum community”.
Best regards,

Very nice website!
Can you please add High Precision Devices (HPD) to the “Private/Startup Companies” on your site? Here is a relevant capabilities summary description: “HPD designs and delivers advanced cryogenic instruments and research equipment to support quantum information and superconducting supercomputing development companies. Our systems solutions, including probe stations and scanning probe microscopy, deliver very low temperature and vibration environments with excellent optical and electrical access.”
Hi
Please add Qubitor Pte Ltd, Singapore. It is a Quantum computation lab where it develops quantum based applications especially in Machine Learning and AI.

Kindly add CogniFrame to the list.
CogniFrame Financial Service OS is built on top of D-Wave’s cloud offering, solving often intractable and computationally intensive non-convex and stochastic optimization problems.
Thanks
Vish
Thank you for your comments. We have added CogniFrame to this list of Private/Startup companies.

Hi Doug,
Congratulation for your excellent website!
Quantum Computing & AI Research (QCAR) is the first Quantum computation related research private company in Taiwan.Currently we are focusing on modeling new topological qubits , we believe it is important to keep up the footsteps of these giant company/ research facilities and serve as a consultant for all potential startup companies not only in Taiwan but around the globe.
Hello Doug,
Great list. Thank you for compiling. Can you please add Quacoon (www.quacoon.com) to the list as a consulting provider?
Thank you,

Look like the quantum factory website is down. Not sure the company is still running or not.
https://quantum-factory.de/
And the website link for Oxford Ionics is wrong.
Their official link should be
https://www.oxionics.com/
Thank you for your comments. We have updated the website link for Oxford Ionics and we are checking into Quantum Factory to see why that website is not working. We appreciate your letting us know about these issues.

NYC cybersecurity startup focused on securing communications with open source software and proprietary quantum hardware.
Thanks for letting us know about Quantum Trilogy. We have added them to this list.

Hi Doug,
We blueqat established spin out startup “BosoniQ” for photonics quantum computing SDK and applications. We started to provide continuous variable programming SDK “photonqat”. The mission is “Solve with lightspeed”.
https://www.bosoniq.net/
Is it possible to add to the list? We already got some angel funding.
Thank you.
Please add Kipu to this list as a Startup under the „multiple“ category – thx!
Thank you for your comment. We have added Kipu Quantum to this list.

Should probably add Quantinuum to this list (spin-off/merger of Honeywell’s Quantum group and Cambridge Quantum Computing)
Startup TuringQ focused on building photonic quantum computing hardware http://www.turingq.com
Thank you for your comments about Quantinuum and TuringQ. We have replaced the individual listings for Honeywell and Cambrdige Quantum with Quantinuum and have added TuringQ to this list.
