Quantum X Labs Announces Cyber Quantum Encryption Breakthrough in Demonstration ...

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

Quantum X Labs Inc. , a quantum technology company developing quantum computing, quantum sensing, quantum error correction and quantum applications technologies, 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 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 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.

Quantum X Labs Demonstrates New Quantum Encryption Scheme on IBM Processor Quantum X Labs has successfully demonstrated its Qatacomb quantum encryption scheme using an IBM Quantum Heron r2 processor. In this demonstration, the intended recipient was able to recover an encrypted image with over 90% accuracy, while an adversary without the key gained no usable information. This marks a significant advancement in quantum encryption, as Qatacomb is designed to provide information-theoretic security, independent of an adversary's computational power. The demonstration utilized a 156-qubit quantum machine and was programmed through IBM's Qiskit framework. Quantum X Labs aims to transition Qatacomb from theoretical to practical applications, potentially safeguarding against future quantum computing threats to current encryption methods. The company emphasizes that this encryption method does not rely on the difficulty of mathematical problems, which are vulnerable to quantum attacks. 3 sources 21
