Multimode Continuous-Variable Quantum Key Distribution with CMOS-Compatible Photonic-Electronic Integration

Multiplexing and photonic-electronic integration offer a route to scalable and high-throughput quantum key distribution QKD networks through parallel transmission and compact hardware suited to volume manufacturing. Realizing this route requires multichannel transmitters and receivers, and a...

Buffer-Qubit-Based Quantum Circuit Allocation Method against Crosstalk Attacks

Quantum Multi-Programming QMP enables the simultaneous execution of quantum circuits from multiple users on a single quantum chip in cloud quantum computing services. However, QMP is vulnerable to crosstalk attacks, in which a malicious user deliberately induces crosstalk to disrupt other users'...

A Robust Digital Receiver Architecture for Continuous-Variable Quantum Key Distribution

Continuous-variable quantum key distribution utilizes advanced digital signal processing techniques to mitigate channel impairments, driving the progress of high-performance quantum secure communications. Specifically, digital heterodyne receivers are commonly implemented using down-conversion...

Security Implications of Measurement Based Crosstalk on Superconducting Quantum Computers

Crosstalk is one of the major issues for scalability of superconducting quantum processors. But it can also be used by threat actors to intentionally sabotage computations and steal information. This paper analyzes data leakage due to crosstalk during qubit measurement. Prior research yielded an...

Pulse-Level Simulation of Crosstalk Attacks on Superconducting Quantum Hardware

Hardware crosstalk in multi-tenant superconducting quantum computers poses a severe security threat, allowing adversaries to induce targeted errors across tenant boundaries by injecting carefully engineered pulses. We present a simulation-based study of active crosstalk attacks at the pulse level...

CVE-2012-1361

Cisco IOS 15.1 and 15.2, when the Multicast Music-on-Hold MMoH feature of Cisco Unified Communications Manager CUCM is enabled, allows remote attackers to obtain sensitive crosstalk information by listening during a PSTN call, aka Bug ID CSCtx77750...

Security Vulnerabilities in Quantum Cloud Systems: a Survey on Emerging Threats

Quantum computing is becoming increasingly widespread due to the potential and capabilities to solve complex problems beyond the scope of classical computers. As Quantum Cloud services are adopted by businesses and research groups, they allow for greater progress and application in many fields...
