Quantum Computing: Bridging the Gap from Theory to Practical Application
Quantum computing holds varying perceptions within the tech community; some view it as a far-off aspiration, while others see it as a burgeoning reality. At this year’s Defcon security conference in Las Vegas, much of the attention is on evolving research and threat assessments. However, Quantum Village co-founders Victoria Kumaran and Mark Carney are making strides to enhance accessibility to existing quantum technology for hackers and technology enthusiasts alike.
During a key presentation on Saturday, Kumaran and Carney will unveil an open-source and cost-effective quantum sensor designed for diverse applications, ranging from medical technologies to alternatives for GPS. This innovation utilizes a unique yet affordable diamond characterized by specific atomic properties. The initial model can be constructed for approximately $120 to $160, depending on available suppliers and shipping logistics. The new iteration they will showcase this weekend is not only more affordable but sets the stage for a third version, expected to be available this fall, which they anticipate could be built for as little as $50.
Quantum sensors are capable of detecting minuscule changes in magnetic and electrical fields, which allows for precise measurements. For instance, atomic clocks, renowned for their accuracy, function as quantum sensors and have been in operation for many years. However, the barriers to entry for accessing quantum sensing technology have been steep. The Quantum Village’s open-source “Uncut Gem” project aims to lower these barriers, enabling a broader audience to construct and experiment with their own quantum sensors.
Kumaran emphasizes the transformative potential of these sensors, noting their capacity to facilitate advancements such as portable MRI-style devices for use in diverse environments. The materials employed in these sensors include synthetic diamonds with inherent defects, an attribute that underscores their practicality and cost-effectiveness. The diamonds utilized must have “nitrogen-vacancy” characteristics, derived from nitrogen atoms replacing carbon atoms within the diamond structure.
Beyond medical applications, quantum sensors can enhance navigation technologies that rely on monitoring electromagnetic wave interference. This could prove invaluable as a local alternative to GPS, particularly during instances of global system failures or electromagnetic jamming. Notably, the U.S. Space Force is currently evaluating a cutting-edge quantum inertial sensor that has achieved performance milestones in space.
For the majority lacking access to premier quantum sensors, the Uncut Gem initiative exemplifies a significant effort to democratize quantum sensing technology. This endeavor aligns with ongoing movements in various hacking domains that prioritize accessibility and low-cost designs.
Independent researcher Davide Gessa is currently evaluating the schematics and code for the Uncut Gem project, further contributing to its development and potential applications in the field. As the landscape of cybersecurity continues to evolve, initiatives like this may not only foster innovation but also pave the way for new approaches to secure technological applications in an increasingly complex digital environment. This can be particularly relevant as organizations assess their defenses against increasingly sophisticated adversary tactics, as outlined in the MITRE ATT&CK framework.
