PacketLight Networks and NEC Demo Quantum-Safe Networking
We begin with PacketLight Networks and NEC Corporation, which demonstrated a working setup for quantum key distribution. Their test used NEC’s quantum key distribution gear alongside PacketLight’s PL-4000M Muxponder. The system maintained 100% data speeds while layering quantum encryption on a separate fiber. It did not need hardware upgrades, which could lower cost barriers for future rollouts.
While still a lab test, the result confirms that QKD can work with today’s commercial networks. This supports secure communications without major changes to data flow. The exhibition also highlights early demand for QKD-compatible hardware and low-latency encryption options.
SEEQC Expands U.S. Operations to Support Chip Design
Next up is a $60 million Nvidia (NVDA)- and IBM Quantum (IBM)-backed startup, SEEQC, which has leased a 13,635-square-foot site in Hawthorne, New York. The space will support chip manufacturing, testing, and system design. The firm builds superconducting chips that can work with multiple quantum systems.
The move gives SEEQC closer access to talent and partners. It also signals its intent to scale chip production for commercial use. The site will house offices and labs that support new designs for modular and stackable quantum computing hardware.
Quantinuum Adds R&D Hub in New Mexico
The biggest standalone quantum company, Quantinuum, will convert a site in Albuquerque into a new research and development hub. The company plans to focus on photonics control, a key part of its laser-based ion-trap quantum systems. The facility is expected to employ at least seven people by the end of the year, with future plans to install test beds.
Quantinuum, formed from Honeywell Quantum and Cambridge Quantum, is one of the few firms that build both quantum hardware and software. Its expansion into New Mexico also supports public efforts to attract more quantum jobs to the Southwest.
IonQ and Oak Ridge Show Quantum-Classical Grid Optimization
IonQ (IONQ) has partnered with Oak Ridge National Laboratory to apply its quantum system to the Unit Commitment problem. This challenge involves scheduling power plants to meet demand at the lowest cost. The project used IonQ’s 36-qubit Forte Enterprise quantum system, in combination with classical models.
The work is part of the U.S. Department of Energy’s GRID-Q program. It tested the ability to optimize energy use across 26 generators and 24 time slots. The results point to potential cost savings and new ways to manage energy supply. IonQ expects future systems with 100 to 200 qubits could outperform current grid planning tools.
Fujitsu Plans 10,000-Qubit System by 2030
Fujitsu (FJTSY) announced plans to build a superconducting quantum computer with over 10,000 qubits by fiscal 2030. The target includes 250 logical qubits using its STAR architecture. The effort is part of Japan’s national post-5G development program, and includes support from RIKEN and AIST.
Fujitsu will also pursue diamond spin-based qubits by 2035. It aims to build a system with 1,000 logical qubits that combine multiple qubit chips. The roadmap includes new work on chip interconnects, cryogenic controls, and error correction techniques.
We used the TipRanks’ Comparison Tool to line up some of the top quantum stocks with a few names mentioned in this piece. It’s an easy way to see how they compare and get a feel for where the space might be going.
Investor Takeaway
This week’s news shows a growing mix of hardware investment and applied use cases. Companies are starting to bridge lab-grade quantum systems with enterprise needs. Quantum-safe encryption, grid optimization, and chip design are moving forward without major changes to core infrastructure.
Investors should watch for continued signs of progress in system integration, facility builds, and commercial partnerships. Cost efficiency, deployment scale, and ecosystem access remain key factors for future gains in this sector.
