Quantum Science and Technologies

In the early part of the 20th century, the discovery of quantum mechanics was a revolution in how scientists understood the world.

Today, in the early part of the 21st century, a second quantum revolution is unfolding, where exotic quantum phenomena unimaginable even a decade ago can be realized and studied given emerging experimental capabilities, and quantum effects can be harnessed for game changing technological applications.

Activities

Quantum efforts at ICFO are at the forefront of today’s research on both fundamental quantum science and novel quantum technologies, covering areas such as:

Quantum Communications and Quantum Internet

Encryption & protocols for secure communications & cybersecurity; quantum repeaters & quantum-memories for long distance quantum communications & the future quantum internet; quantum random number generators, highly efficient sources of polarization-entangled photons, & device-independent quantum information processing & quantum certification.

Quantum Processing and Quantum Artificial Intelligence

It is a fundamental question whether the schemes based on quantum mechanics can be used for classical information processing and machine learning. ICFO exploration of new avenues to solve computational problems in optimization & machine learning, using quantum or quantum-inspired hardware accelerators.

Quantum Atomic and Optical Sensors

Employing quantum processes arising from light-atom interactions in various platforms, including hot-vapor, laser-cooled, & ultra-cold atomic systems. ICFO has pioneering work on ultrasensitive quantum atomic clocks & gyroscopes, portable quantum atomic optical magnetometers for magnetic resonance diagnostics, & chip-scale and integrated miniaturized atomic devices.

Low-dimensional Quantum Materials

We explore low dimensional materials such as graphene, hBN, MoS2, NbSe2 , investigate their interactions with light at the nano-scale, and develop scalable technologies based on colloidal quantum dots as single photon emitters and single photon detectors. Also, ICFO explores novel quantum computing approaches, such as with the realization of carbon nanotube mechanical qubits.

Synthetic Quantum Matter for Quantum Simulation

Developing software and/or hardware to exploit engineered quantum systems  (ultracold atoms, solid-state systems) as quantum simulators, quantum optimizers/annealers, and special purpose quantum computing devices capable of solving problems that are out of reach for classical supercomputers. 

 

Fundamental Quantum Science

Creating novel quantum tech requires a deep understanding of quantum phenomena, such as entanglement and Bell nonlocality, from detection to manipulation and its use. Interactions between many quantum particles lead to the emergence of novel collective quantum phenomena, such as superfluidity, superconductivity & quantum magnetism, which are behind challenges in fundamental quantum physics & quantum tech applications. ICFO works in quantum, nonlinear and nano-optics & quantum many-body physics.
