IonQ to Acquire Zero-Trust Security Firm Elisity in Deal Worth Up to $1.3 Billion

IonQ has signed a definitive agreement to acquire Elisity, a provider of software-defined Zero Trust (a security model that verifies every access request rather than trusting the network perimeter) policy tools. The all-stock deal is valued at up to $1.3 billion, including up to $150 million in performance-contingent earnouts, and is expected to close in the fourth quarter of 2026. Elisity would operate as a subsidiary under its existing brand and management. IonQ says it plans to combine its post-quantum cryptography (PQC) and quantum key distribution (QKD) technology with Elisity’s policy engine, adding cryptographic inventory and risk data to help organizations manage “harvest now, decrypt later” threats during multiyear PQC migrations. The transaction follows IonQ’s earlier acquisitions of ID Quantique and SkyWater Technology and remains subject to closing conditions.

DOE Names Eight Priority Science Problems to Guide Its Fault-Tolerant Quantum Push

The U.S. Department of Energy (DOE) has announced its Quantum Genesis Priority Applications: eight scientific problems meant to steer the effort to build the first fault-tolerant, scientifically useful quantum computers. They fall into four domains — chemistry (reaction mechanisms and light-driven processes), materials (quantum and extreme-environment materials), subatomic physics (nuclear interactions and high-density matter) and applied mathematics (linear and differential equations). The list is intended to bring domain scientists together with quantum researchers and to benchmark quantum performance against leading supercomputing methods, and it informs the program’s three pillars: the Q Competition, a National Quantum Computing User Facility and applications research. DOE says it is working with the Department of War, the Laboratory for Physical Sciences and NASA on broader applications efforts. The announcement does not specify problem sizes or timelines.

Auckland-Led Team Builds Octave-Spanning Microcomb on a Single Photonic Chip

Researchers at the University of Auckland, working with the National Institute of Standards and Technology (NIST), the University of Maryland and the University of California, Santa Barbara, report in Nature a self-aligned optical frequency comb (a “light ruler” of evenly spaced frequencies) that spans an octave on a foundry-fabricated chip. Instead of spreading light outward from one laser, the design uses two pump lasers an octave apart, with the frequencies in between filling in automatically. The team used it to read out an integrated optical clock, generate precisely spaced optical frequencies and produce low-noise millimetre-wave signals. Potential uses include portable atomic clocks, GPS-free navigation and precision quantum sensing; the work is a laboratory demonstration, and a provisional patent has been filed.

IonQ Researchers Propose Scheduling Scheme That Speeds Up Logical Gates on qLDPC Codes

In an arXiv preprint, IonQ researchers Mark Webster and Nicolas Delfosse describe a hybrid physical/logical execution strategy for qLDPC (quantum low-density parity-check) error-correcting codes. It replaces sequential logical measurements with joint measurements scheduled by classical scheduler codes, using cat states (Shor-style entangled ancilla states), to cut the round delays that slow logical operations on densely packed registers. In simulations on the authors’ Q102 code, random logical Clifford circuits ran up to 74.4 times faster and logical Toffoli gates up to 5.0 times faster than the baseline. These are theoretical results from a preprint that has not yet been peer reviewed or demonstrated on hardware.
