Can I Trust You? Let’s Flip a Coin
How can two mistrustful parties fairly toss a coin? As it turns out, this problem of weak coin flipping (WCF) is a fundamental cryptographic primitive, where quantum WCF can achieve theoretically perfect information security over modern communication networks.
In a recent paper, researchers from Sorbonne Université, the University of Vienna, California Institute of Technology and Université de Paris have — for the first time — experimentally demonstrated this primitive. Among a number of conceptual and practical challenges, such a demonstration was made possible thanks to the use of high-efficiency Superconducting Nanowire Single-Photon Detectors (SNSPDs). The team used ID Quantique’s ID281 Series SNSPD system.

ID281 Superconducting Nanowire Series
The ID281 series features the very best in single-photon detection, with ultra-stable performance, including:
- Near-ideal detection efficiency: can exceed 95%
- Highly precise timing and low noise, true latch-free operation
- Ultrafast and photon-number resolving detection
- Mix and match up to 16 detectors, with options for rack-mounted systems
