Second Generation Quantum Devices

Second-generation quantum devices represent the transition from foundational demonstrations of quantum phenomena to functional, scalable technologies that harness quantum effects for real-world applications. While first-generation devices focused primarily on proof-of-principle experiments—such as basic qubit manipulation or quantum key distribution—second-generation systems emphasize integration, reliability, and performance. These devices aim to exploit controlled quantum coherence and entanglement to achieve computational, sensing, and communication capabilities beyond classical limits. Examples include near-term quantum processors implementing error mitigation, hybrid quantum–classical algorithms for material and molecular simulations, and advanced quantum sensors with unprecedented precision. The development of these devices marks a key step toward the quantum advantage era, where quantum technologies begin to deliver tangible benefits in scientific research, secure communication, and industrial innovation.

In our research team is mainly interested on quantum devices for quantum information, quantum metrology and energy storing quantum devices (AKA quantum batteries). We invite you to check our work on Quantum Charging Advantage in superconducting batteries and the proposal of a Quantum Wheatstone Bridge, the quantum version of the classical Wheatstone Bridge.
