In anticipation of our merger with dMY Squared, Horizon Quantum is announcing expected new members of our board of directors and a key addition to our leadership team. 

Horizon Quantum and Alice & Bob announced a strategic collaboration to leverage both companies’ strengths and streamline the development and deployment of fault-tolerant quantum computing software.

Horizon Quantum today announced the debut of Beryllium, a hardware-agnostic, high-level language for programming quantum computers.

Horizon Quantum and dMY Squared announced that they have entered into subscription agreements with investors for a $110 million PIPE financing comprised of common equity, priced at the SPAC redemption price per share, to support the previously announced proposed business combination which is expected to close in the first quarter of 2026.

Horizon Quantum today announced that it has completed the assembly and integration of a first quantum computer at its Singapore headquarters. The system is now fully operational.

Subject to the completion of the SEC review process and satisfaction of customary closing conditions, including the approval of dMY’s and Horizon’s shareholders, Holdco’s Class A ordinary shares and warrants are expected to be listed on the Nasdaq Stock Market under the symbols “HQ” and “HQW” upon the closing of the transaction.

Transaction expected to significantly accelerate Horizon Quantum’s development of the software infrastructure to power the future of quantum computing.

Horizon Quantum announced the appointment of Greg Gould to the role of Chief Financial Officer. Greg will lead key financial initiatives that are a part of Horizon Quantum’s long-term strategic growth plan.

Horizon Quantum and QuEra Computing, the leader in neutral-atom quantum computing, today announced that Horizon Quantum has joined the QuEra Quantum Alliance.

Horizon Quantum and dMY Squared, a publicly traded special purpose acquisition company led by Harry You, jointly announced today that they have entered into a non-binding letter of intent for a business combination.

Our CEO Dr Joe Fitzsimons took the stage at Q2B Silicon Valley to showcase the progress we’ve made in 2024, and demonstrate new and upcoming capabilities in Triple Alpha.

The program is an ecosystem of quantum computing hardware, software and service providers who build and offer integral components of a functional quantum computing system.

The system, which is expected to be installed by early 2025 will be controlled by the OPX1000 platform from Quantum Machines and integrated with our software development environment, Triple Alpha.

Horizon Quantum Computing, a company building software development tools for quantum computers, today announced that it is establishing a first-of-a-kind testbed for integrating quantum computing hardware with its software stack, Triple Alpha. The testbed, which will be set up at Horizon’s Singapore headquarters, will have the capacity to host multiple quantum computers.

Horizon is delighted to become part of the Surge community, aligning with the Surge 09 cohort.

The Trinity Quantum Alliance is a new collaboration that brings together experts from research and industry, and which will provide a new custom space in Trinity East for innovative projects in quantum science and technology, simulation, education and computation in Ireland.‍

Singapore, 31 March 2023 – Horizon Quantum Computing, a Singapore-based company building software development tools to unlock the potential of quantum computing hardware, announced today that it has raised USD 18.1 million Series A investment from Sequoia Capital India, Tencent, SGInnovate, Pappas Capital and Expeditions Fund.

The Dublin office will be Horizon’s first outside of Singapore. Horizon Quantum Computing’s expansion is part of its growth plan to leverage skilled quantum computing and software engineering talent in the region. It looks to benefit from the wealth of talent and serve customers in Europe, one of the world's major markets for quantum computing.

As part of its 20th-anniversary celebrations, the Singapore Businesses Federation launched the book ‘20 Conversations’. Deputy Prime Minister Mr Heng Swee Keat was the guest of honour at the event along with the attendance of 100 business leaders, trade associations and chamber leaders.

Horizon Quantum Computing, a Singapore-based company providing software development and deployment tools for quantum computing applications, is to become a node on the National Quantum-Safe Network (NQSN) announced by the National Research Foundation, Singapore, and the National University of Singapore (NUS).

As quantum computers become ever more powerful, how can we be sure that the answers they return are accurate? A team of physicists, including Horizon’s CEO Joe Fitzsimons, have developed a new method to use one unreliable quantum processor to verify another and implemented it on five different quantum processors.

Marie-Christine Roehsner, Joshua A. Kettlewell, Joe Fitzsimons (Horizon’s CEO) and Philip Walther, engineered and experimentally realized a new protocol for running probabilistic one-time programs on a quantum computer that resolved major drawbacks of all previously known schemes. By encoding classical software in small quantum states, the team was able to design and successfully execute single use copies of quantum software.

Quantum algorithms for practical machine learning models can load data from QRAM in constant time without violating the search lower bound. The study, published in Quantum Machine Intelligence Journal, was conducted by Jansen Zhikuan Zhao, Jack F., Patrick Rebentrost, Vedran Dunjko and Joe Fitzsimons (Horizon’s CEO).

This new approach doesn’t require any communication between the client and server once the data has been passed off, while providing some data security for a variety of quantum computations. The study was conducted by Jonas Zeuner, Ioannis Pitsios, Si-Hui Tan (Horizon's CSO), Aditya N. Sharma, Joe Fitzsimons (Horizon's CEO), Roberto Osellame and Philip Walther.

Today we announce that we have increased our seed financing to SGD 4.5 million (USD 3.23 million) thanks to a seed-plus round led by Sequoia Capital India with participation from previous investors SGInnovate, Abies Ventures, DCVC, Qubit Protocol, Summer Capital and Posa CV. The additional funding will allow us to accelerate the speed at which we can bring our innovative technology to market, to further engage with customers and early adopters and to continue strengthening our team.

Today we are delighted to announce that we have secured seed funding, in a round led by SGInnovate, to help us make this vision a reality. We are looking forward to working with SGInnovate, as well as with the other investors in the round, including Abies Ventures, Data Collective, Qubit Protocol, Summer Capital and Posa CV.

Today we are delighted to announce that we have entered into a partnership with Rigetti Computing. At Horizon Quantum Computing, we are building a new generation of programming tools that will allow developers with little or no prior exposure to quantum computing to harness the full power of quantum processors.
