Quantum Information Science, built on the foundations of quantum mechanics, which is one of the pillars of 20th century physics, it's a subject that using the principles of quantum mechanics of micro-particles to solve the problem of the classic informatics and classical computer can not do, it's a cross subject based on quantum mechanics and information science. Quantum Information Science is mainly contains 2 parts of quantum communication and quantum computation.

The research on quantum information has being made large progress, with the development of information technology and quantum mechanics, there are several physical systems being considered to realize quantum information processing, like Ion Systems, Nuclear Magnetic Resonance Systems, Microcavities Systems, Trapped Neutral Atoms Systems, Ultracold Atoms in Optical Lattices, Micro-trapped Particle Arrays Systems, Solid-state Instruments Systems, optical systems.

Laser has unique quantum characteristics. Since lasers are used as light sources in optical communication to emit coherent light and the number of photons is large, optical communication has obvious advantages in the field of quantum communication.

Qubits and quantum logic gates (referred to as quantum gates) are one of the most basic and important building blocks of quantum computers, because qubits are the basic information carriers and quantum information storage units, and the operation of quantum computers requires It is implemented by quantum logic gates, and in principle all quantum gate operations in quantum computing can be implemented by a combination of a single-bit rotating quantum gate and a two-qubit controlled NOT gate. The two orthogonal polarization states (horizontal polarization and vertical polarization or called O light and E light) of polarized laser photons can serve as two orthogonal states of qubits.

SEAGNOL Photonics supply optical polarization components applied in Quantum Communication systems, and has been tested by worldwide university, research institute, optical quantum communication company, etc., it's our honour to take part in the quantum communication project that is about to change the world.

Some of the main products applied in quantum field:

In Line Polarizer, which can convert the non polariaered light to a polarized light.

Polarization Beam Combiner Splitter, which can combine the two orthogonal polarization light into one output fiber or split the orthogonal polarization light to two output fibers.

Polarization Light Detector, or called PM Pigtailed Photodiode, it can detect the optical power for polarization light.

PM Fiber Fused Coupler, can be used for split the polarization optical light power with different coupling ratio.
