PolyU Develops Quantum-Tunnelling Field-Effect Transistor

Curated by Shubham · TechCapsules · Aug 31, 2026

AI-summarised brief · reviewed before publication

PolyU researchers, led by Prof. Jianhua Hao, have fabricated a two‑dimensional tunnelling field‑effect transistor (TFET) using a Bi/InSe heterostructure grown by pulsed laser deposition. The device surpasses the 60 mV/decade Boltzmann limit, achieving sub‑60 mV subthreshold swing over six orders of current and operating with a 160 mV gate voltage at room temperature on silicon wafers. It delivers microamp‑per‑micrometer output currents and high ON/OFF ratios, demonstrating compatibility with existing CMOS processes and scalability for AI‑accelerator chips.

💡 Why It Matters

· The TFET’s ability to break the thermionic barrier while maintaining high output current signals a practical path toward ultra‑low‑power, high‑performance processors, directly addressing the energy constraints that have stalled Moore’s Law.

Diraq to Deploy Eight-Qubit Silicon Quantum Computer at Equinix Sydney Data Center

Diraq and Equinix announced plans to install an eight‑qubit silicon spin‑qubit quantum processor in an operational Equinix data center in Sydney, Australia, slated for completion in October 2026. The system will occupy a standard server rack, draw under 20 kW, and include a self‑contained cryogenic unit. It is the first silicon‑based quantum computer deployed in a shared commercial data‑center environment, enabling live hybrid quantum‑AI workflows and modular scaling via chip swaps. The partnership aims to benchmark performance, secure networking, and open the facility to enterprise customers after validation.

💡 By embedding a quantum processor in a commercial rack, the deployment demonstrates that quantum computing can coexist with conventional data‑center workloads, potentially accelerating industry adoption and reducing the need for specialized facilities.

QTREX Quantum to Unveil 17,280-Line Cryogenic Interconnect Architecture at IEEE Quantum Week…

QTREX Quantum Ltd. announced it will publicly unveil a 17,280‑line cryogenic interconnect architecture at IEEE Quantum Week 2026 in Toronto. The design uses monolithic additively manufactured electronics (AME) to integrate signal conductors, dielectrics, shielding, and thermal anchoring into a single assembly, replacing discrete coaxial cables. The architecture distributes lines across the perimeter and plate area of each cryogenic stage, aiming to double the density of existing interconnects for commercial dilution refrigerators. QTREX plans post‑event configuration programs to tailor solutions for quantum processors, cryostats, and thermal budgets.

💡 The breakthrough enables scalable, low‑thermal‑load wiring essential for larger qubit arrays, directly addressing a critical bottleneck in quantum hardware development.

Diffraqtion Caps Pre-Seed Round at $10M+ with Strategic Backing from Lockheed Martin…

Diffraqtion, an MIT and University of Maryland spin‑out, announced an expanded pre‑seed round exceeding $10 million, led by Lockheed Martin Ventures and Presidio Ventures and joined by existing investors such as Ground State Ventures and Collaborative Fund. The Massachusetts‑based startup is developing a quantum‑enabled optical camera that bypasses the diffraction limit by sorting light according to spatial mode and applying passive quantum estimation, eliminating the need for qubits or cryogenic cooling. Simulations claim the system can resolve features up to 20 times smaller than conventional optics while delivering rapid, low‑power photonic inference. Recent milestones include on‑sky observatory demos, DARPA and NASA SBIR awards, and a win in NASA’s Space‑to‑Soil Challenge. New capital will fund the first fielded camera and a hosted payload flight to demonstrate space‑domain‑awareness capabilities.

💡 By delivering sub‑diffraction imaging without bulky hardware, Diffraqtion could reshape reconnaissance and debris‑tracking sensors, giving defense and space operators unprecedented detail from compact platforms.
