Quantum Computing Specialist EeroQ Tape-Out 'Wonder Lake' QPU Chip
Quantum Computing specialist EeroQ has successfully taped-out its Quantum Processing Unit (QPU) chip, codenamed 'Wonder Lake,' as it aims to bring its next-generation quantum computing technology to market. Based on a CMOS manufacturing approach, Wonder Lake's qubit count is one of the highest, with 2,432 helium-electron qubits, making it one of the most densely populated QPU designs.
EeroQ's technology is based on quantizing isolated electron spins suspended above pools of liquid helium. The technology utilises an effect known as 'Rydberg states' to turn the motion of the suspended electron into computable representations of 0s and 1s.
The company's new chip is fabricated using CMOS technology, which allows the company to tap into well-understood technology and simplify the fabrication process. The qubits provided by EeroQ have high coherence timeout and qubit connectivity, enabling the acceleration of workloads and the processing of complex circuits. The qubits' mobility across the helium layer also reduces overhead for error correction mechanisms.
EeroQ is still working on demonstrating its two-qubit gate design, a necessary step for a post-NISQ future. However, the company focuses on scalability and achieving many-qubit interactions before extracting utility from limited computing resources.
'This is a major step for EeroQ,' says Anirudh Narayanan, CEO and co-founder of EeroQ. 'We're still focused on proving out our core technology, but recent advances in error mitigation, more efficient algorithms, and scalability will lead to the commercial quantum future coming together sooner than expected.'
In contrast to other quantum computing approaches, EeroQ's solution requires only 30 control lines per chip, reducing control complexity and costs. The company believes that recent advances in error mitigation, more efficient algorithms, and scalability will lead to the commercial quantum future coming together sooner than expected.
'Advances in quantum computing are happening at a faster pace than expected,' says Narayanan. 'Our approach to quantum computing sets us apart from others, and our focus on achieving cost savings in computing area and control system expenses is what will enable us to be the quantum leader.'
The company is still some way from achieving its goal of a 100-qubit QPU, but the technology is getting closer to reality with every step.
