POET-Based Quantum Computing IP

The Company is also announcing a key expansion of its IP asset base. The Company already has a large inventory of key and ancillary patents protecting its unique platform for monolithic fabrication of integrated circuit devices containing both electronic and optical elements on a single semiconductor wafer. Details of the existing portfolio are available through USPTO.

In addition to this portfolio, the Company recently filed for protection a number of new IP classes with USPTO, as well as in Canada, Japan, Korea, and other key jurisdictions.

“The commercialization process of the Company’s POET platform has historically yielded intellectual assets with future commercial development potential meriting IP protection,” said Mr. Copetti. “While the Company has focused assets and effort on near-term commercialization goals, our labs are generating future IP as well.”

The new portfolio includes:

• Closed Loop Rectangular Resonators in POET & Thyristor Memory
  (OPE-069; 14/238,649; PCT/US12/51265; EPO 12824167.6)
• Fiber Optic Coupling Array
  (OPE-070; 14/104,230; PCT/US13/74658)
• Quantum Dot Lasers in POET for 1310-1550 nm Operation
  (OPE-072; 13/921,311)
• Universal Memory Cell in POET for DRAM, SRAM and NVRAM Applications
  (OPE-073; 13/951,578)
• IR Imaging Structures in POET based on Quantum Dot Epitaxy
  (OPE-074; 14/023,525)
• Whispering Gallery Mode Resonators in the Planar OptoElectronic Technology; and Implementation of 1550 nm Optoelectronics in the Planar OptoElectronic Technology
  (OPE-075; PROV 61/962,303; 14/222,841)

Mr. Copetti added, “In this latest round of patent applications, the Company has filed patent protection for IP that, in the medium-to-long-term, supports theoretical quantum computing applications, such as the fabrication of quantum dot-based spin qubits and the devices needed to read and write them on the same die. With POET integrated opto-electronics, we are already ahead of the curve, and we want to stay that way.”

A qubit – also known as a quantum bit – is a unit of information in quantum computing. It is the quantum analogue of a bit in a classical computing system, which would have to be in one of two states. Quantum mechanics allows a qubit to be in a superposition of both states at the same time, a property which is fundamental to quantum computing. The new patent applications are for medium-to-long-term strategic positioning, and they are complementary to the core POET intellectual assets.
