In its first run on a real quantum processor, Quantum X Labs’ Qatacomb scheme successfully recovered an encrypted image using a 156-qubit machine, while an adversary without the key gained no usable information in the demonstration, illustrating a privacy guarantee designed to hold regardless of an adversary’s computing power

TEL AVIV, Israel, Nov. 02, 2026 (GLOBE NEWSWIRE) -- Quantum X Labs Inc. (NASDAQ: QXL) (“Quantum X Labs” or the “Company”), a quantum technology company developing quantum computing, quantum sensing, quantum error correction and quantum applications technologies, today reported the first demonstration of its Qatacomb quantum encryption scheme on commercial quantum hardware.

In a run on an IBM Quantum Heron r2 processor, programmed through IBM's open-source Qiskit framework, the intended recipient reconstructed an encrypted image by reading through the machine's own noise, while an adversary who did not hold the key gained no usable information about the message.

The Company believes the significance lies in the kind of guarantee the scheme is designed to provide. Most encryption in use today rests on mathematical problems that are hard to solve with current computers, and a sufficiently capable quantum computer is widely expected to be able to break much of it. Qatacomb is instead designed so that its privacy follows from the structure of quantum states themselves: it is intended to be information-theoretic, meaning its security is not designed to depend on any assumption about how much computing power an adversary can bring to bear, now or in the future.

The demonstration moves Qatacomb from theory to testing on a real device. The intended recipient, holding the key, recovered the correct content for better than nine of every ten image elements and reconstructed the full image without error - despite the processor's real noise. The adversary's best possible measurement, evaluated exactly, returned no usable advantage.

For example, the Company is using forward-looking statements when it discusses the intended security and privacy characteristics of Qatacomb, including its intended information-theoretic security and its design not to depend on assumptions regarding an adversary’s computing power; the potential significance, capabilities, benefits and applications of Qatacomb and the Company’s quantum encryption technologies; and the Company’s continued development, testing and commercialization of Qatacomb and its other quantum technologies. Forward-looking statements are not historical facts, and are based upon management’s current expectations, beliefs and projections, many of which, by their nature, are inherently uncertain. Such expectations, beliefs and projections are expressed in good faith. However, there can be no assurance that management’s expectations, beliefs and projections will be achieved, and actual results may differ materially from what is expressed in or indicated by the forward-looking statements.
