Leading Quantum
Internet Technology
Toward the Realization of a Completely Secure Quantum Internet
With the commercialization of quantum computers, conventional cryptography will be instantly cracked,
and all
information flowing over the Internet will be at high risk.
LQUOM is developing long-distance quantum communication technology to provide a completely secure
Internet in the areas
of finance, telemedicine, and defense.
WHO WE ARE
LQUOM is developing long-distance quantum communication technology to commercialize the completely secure quantum Internet, a next-generation network.
Currently, there is a lot of confidential information being communicated through the
Internet, including passwords,
credit card information, and confidential corporate information.
The content of these communications seems to be protected by encryption, but in fact,
the encryption can be deciphered
with the use of high-performance computers.
While conventional computers require much time to decipher the information, with the
development of quantum computers
and such technologies, which can process information more rapidly, there is a fear that
the Internet may suddenly stop
functioning due to a swarm of cyber-attacks such as unauthorized logins and personal
information leaks.
In order to eliminate such dangers, a quantum internet using completely secure in theory quantum communication technology is necessary. When quantum communication is eavesdropped, the quantum state changes according to the physical laws of quantum mechanics making it possible to detect eavesdropping. However, because it is necessary to use photons, which are extremely weak light, it is not possible to use the repeaters (amplifiers) used on the fiber-optic Internet.
On the other hand, relaying is desirable for secure communication over long distances, and a “quantum repeater” dedicated to quantum communication is essential for realizing the quantum Internet. LQUOM possesses all the elemental technologies necessary to develop a quantum repeater and is currently developing a prototype for demonstration by 2023.
A quantum repeater must have the ability to send a quantum to a distant location without destroying it. Furthermore, LQUOM is developing a quantum repeater with a routing function (a function to select a network route) similar to the conventional Internet. The routing function is the basis of the Internet today, and it allows multiple devices to communicate, rather than one-to-one communication. Additionally, this function can be used to divert to a safe route when eavesdropping is detected. The basis for this is cutting-edge physics, such as quantum teleportation and quantum entanglement swapping.
LQUOM is accelerating its developments with the aim of commercialization and becoming a global leader in the quantum Internet.
Origin of the Company Name
We named this group to aim at the development and social implementation of Long-distance Quantum
Communication.
We are the deep tech startup from the Horikiri Laboratory, Yokohama National University, having
all the elemental
technologies, including quantum entanglement generator, quantum memory, wavelength conversion,
and frequency
stabilization.
SCIENCE
Introducing the science and technology behind the quantum Internet that LQUOM aims to realize.
Quantum repeaters, which are the core of the quantum Internet, require core technologies, including an entangled photon source that emits photons for quantum communication and sends quantum states through optical fibers; a quantum memory that temporarily stores quantum states; and wavelength conversion/frequency stabilization that connects the light source and the memory. In other words, the core elemental technologies are (1) quantum light source, (2) quantum memory, and (3) frequency stabilization, and the integration of these technologies is the key to a quantum repeater. LQUOM possesses all these core elemental technologies.
PRODUCTS
LQ-PS-100 is a cavity-enhanced two-photon source with an optimal design for the quantum repeater with Pr: YSO quantum memory.
