Latest Patents

**Method for polarization alignment.** This invention describes aligning polarization in optical communication, quantum cryptography, and quantum computing systems. A source generates polarization-entangled photon pairs and sends them through separate quantum channels to two detection modules. Each module measures photon polarization in two non-orthogonal bases, while a compensation unit addresses polarization changes introduced during transmission. The alignment is performed using a downhill simplex algorithm, a deterministic algorithm, or both.

**Method for quantum communication.** This invention describes communication among at least three receivers using photons generated in spectrally separated signal and idler wavelength ranges. Signal photons are sent to a first receiver, idler photons to a second receiver, and both types of photons to additional receivers. Each receiver connects to the source through a quantum channel, enabling communication among the receivers.

Career Highlights

Zannotti’s listed inventions address practical challenges in quantum networks, including compensating for polarization changes in transmission and distributing photons among multiple receivers. Both patents concern systems designed to support quantum communication applications.

Collaborations

Zannotti is associated with Quantum Optics Jena GmbH. His listed coworkers include Oliver De Vries and René Heilmann.

Conclusion

Alessandro Zannotti’s patent portfolio reflects work on polarization control and multi-receiver quantum communication, two important areas in the development of quantum technologies.
