en.Wedoany.com Reported - Quantum computing company Planckian officially announced on May 14 the appointment of Seth Lloyd, Professor of Mechanical Engineering at the Massachusetts Institute of Technology (MIT) and a pioneer in quantum computing, as a Founding Researcher. Professor Lloyd will lead the development of quantum error correction strategies for Planckian's global control architecture, a move aimed at removing a fundamental obstacle to building fully error-corrected, large-scale quantum computers.
This appointment builds upon a scientific exchange spanning over two decades. Planckian's global microwave drive architecture is directly derived from the concept of "global control quantum computing" proposed by Professor Lloyd in a 1993 Science journal paper. That paper first demonstrated that multiple qubits could be operated through a shared control structure, rather than relying on one-to-one dedicated control lines. This idea constitutes the theoretical origin of Planckian's technical roadmap. Company co-founder and CEO Michele Dallari commented that when building the company's scientific foundation, Seth's 1993 paper was a natural starting point, and the notion of global control as the basis for scalable quantum computing has shaped the team's way of thinking about the problem from the very beginning.
Currently, most quantum computing hardware is based on a "dedicated control line per qubit" design. As the number of qubits increases, wiring complexity has become the primary scaling bottleneck. Planckian's solution employs global microwave drive, and its chip architecture ensures that control lines do not increase linearly with the number of qubits, aiming to fundamentally eliminate this bottleneck. In a statement, Professor Lloyd said that Planckian's unique architecture based on global control overcomes one of the major obstacles to building fully error-corrected, scalable quantum computers, and a clear path exists to realize this vision.
The core task of this collaboration is to develop a quantum error correction scheme specifically adapted to the global control architecture. Traditional error correction codes typically operate under a "per-qubit independent control" model, whereas Planckian's global operation characteristics require a customized design for the error correction logic. Professor Lloyd's role is to leverage his decades of experience in quantum information theory to embed the error correction logic into the system's underlying architecture, rather than applying it as an afterthought patch. The company emphasized that as quantum systems grow in scale, error correction and architectural design have become inseparable, a layer that simultaneously requires the theoretical depth and practical judgment that Professor Lloyd provides.
Seth Lloyd is one of the founding figures in the field of quantum information science and the first researcher to propose a technologically feasible concept for a quantum computer. He currently serves as a Professor of Mechanical Engineering at MIT and a Principal Investigator at the Research Laboratory of Electronics, and is the author of the book Programming the Universe. His over 200 academic papers in the fields of quantum computing, quantum communication, and quantum feedback control have laid key foundations for the industry's development.
Planckian is a deep-tech company co-incubated by the University of Pisa and the Scuola Normale Superiore di Pisa in 2023, headquartered in Pisa, Italy. The company focuses on developing superconducting quantum processors centered on a global control architecture, aiming to solve the fundamental scaling challenges currently facing the quantum computing industry. This appointment comes as Planckian actively seeks technological breakthroughs, with the company recently continuing to expand its hardware and design capabilities through recruitment and other means.
