France’s Pasqal has achieved a significant milestone by introducing its neutral-atom quantum computing technology on the Microsoft Azure Quantum cloud platform. This marks a groundbreaking development as it is the first instance of a neutral-atom quantum computer being made available through Microsoft’s services. The collaboration between Pasqal and Microsoft aims to democratize access to quantum technologies, enabling businesses and researchers to leverage Pasqal’s advanced quantum computing capabilities via the cloud. This move eliminates the need for substantial infrastructure investments typically associated with acquiring quantum computers.
Pasqal’s quantum computer is based on neutral-atom technology, offering a unique set of analog quantum computational functions. Each quantum bit (qubit) is represented by a single neutral atom with distinct electronic energy levels corresponding to the 0 and 1 states. These atoms are confined in an “atomic registry” using optical tweezers, allowing computations to be performed by applying precise laser pulses. Unlike many existing quantum technologies that require supercooling, Pasqal’s quantum computer operates at room temperature, enhancing its practicality and accessibility.
Although the exact number of qubits available in the cloud-based quantum offering has not been disclosed, Pasqal’s innovative approach has garnered recognition. The company, established in 2019, boasts a distinguished co-founder, Professor Alain Aspect, a Nobel Prize laureate in 2022 for his groundbreaking work on entangled photons. In January 2023, Pasqal secured $108 million in funding, enabling further advancements in quantum computing technology and expanding its global presence with installations in Saudi Arabia and Germany.
On the other hand, Microsoft introduced Azure Quantum in 2021, supporting various quantum hardware architectures from partners such as Quantinuum, IonQ, and Atom Computing. Recently, Microsoft unveiled the Majorana 1 quantum processing unit, featuring a topological core and named after the Majorana particle. This chip operates near absolute zero temperatures and incorporates topological superconducting nanowires with Majorana Zero Modes (MZMs) at the wire ends, signifying a significant leap in quantum computing capabilities.
The collaboration between Pasqal and Microsoft signifies a pivotal moment in the advancement of quantum computing technology, paving the way for enhanced accessibility and utilization of quantum resources. This strategic partnership underscores the commitment to innovation and the democratization of cutting-edge technologies, positioning both companies at the forefront of the quantum computing revolution.
