Terra Quantum, a prominent quantum technology company, announced a groundbreaking achievement in the field of superconductivity. In a recent publication in the Advanced Quantum Technologies journal, the company revealed the first-ever observation of room-temperature superconductivity in graphite.
Superconductivity, the ability of conductors to carry electric current without resistance, was first discovered by Dutch physicist Heike Kamerlingh Onnes in 1911. However, until now, this phenomenon was only observed at extremely low temperatures. The breakthrough by Terra Quantum’s Chief Technology Officer Professor Valerii Vinokur, along with Cristina Diamantini from the University of Perugia and Carlo Trugenberger from SwissScientific Technologies, demonstrates superconductivity at room temperature.
The findings are a momentous milestone in the scientific community. “Our work is an experimental discovery that humankind has been waiting for about a hundred years since the first observation of superconductivity in mercury,” said Prof. Valerii Vinokur. This breakthrough opens up new possibilities for various industries.
Markus Pflitsch, the founder and CEO of Terra Quantum, envisions transformative advancements across multiple sectors. “Room-temperature superconductivity opens a gateway to spectacular advances in superconducting technology,” he said. Pflitsch highlights the potential for power grids with minimal energy loss, revolutionary healthcare diagnostics through enhanced MRI technologies, energy-efficient high-speed trains utilizing magnetic levitation, and electronics entering a new era of miniaturization and power efficiency.
Moreover, the emerging field of quantum computing stands to benefit significantly from this discovery. “The qubits that now operate only at 10-20 mK can come to room temperature functioning. Thus, the things that were viewed as futuristic dreams have become a reality,” added Prof. Vinokur.
The research team at Universidade Estadual de Campinas, led by Prof. Yakov Kopelevich, used a fascinating approach to unlock room-temperature superconductivity. They utilized scotch tape to cleave pyrolytic graphite, a manufactured form of graphite, into thin sheets. These sheets contained dense arrays of wrinkles arranged in nearly parallel lines. The unique geometry of these wrinkles facilitates the pairing of electrons and enables the flow of superconducting currents along the wrinkles.
The mechanism behind this superconductivity phenomenon involves the formation of condensate droplets on the surface of graphite. These droplets create an effective Josephson junction array, representing a new type of topological Bose metal state. The defects on the surface play a crucial role in enabling superconductivity by suppressing dissipation caused by quantum phase slips.
This breakthrough discovery of room-temperature superconductivity in graphite brings us one step closer to harnessing the incredible potential of this phenomenon for practical applications. With further research and development, we may soon witness the widespread integration of superconducting technologies in our everyday lives, revolutionizing the way we harness and transmit electricity, diagnose illnesses, and propel transportation systems into the future.
