Time-Bin CKA as a tool for blockchain technology

At Quantum Blockchains, our pursuits extend beyond the daily enhancements of our Quantum Secured Blockchain and Quantum Cryptography Migration System. We are consistently envisioning the horizon of technological advancements. We firmly believe that the realm of quantum information science holds the key to a truly efficient and reliable blockchain consensus protocol.

Our recent publication on ArXiv delves into the potential of the Time-Bin Conference Key Agreement (TB CKA) protocol as an avenue for achieving consensus among multiple parties.

Our paper elucidates the potential physical implementation using the time-bin entanglement protocol and exemplifies how this procedure can be perceived as a quintessential realization of the global common coin primitive. Following this, we demonstrate how TB CKA can be integrated into classical consensus algorithms, forging hybrid classical-quantum solutions. This innovative approach addresses the Byzantine Agreement challenge, circumventing the well-known blockchain consensus hurdles presented by the FLP impossibility result and Brewer’s CAP theorem.

Our Patents

Quantum B USA is a company that specializes in quantum computing and related technologies. As of my last training cutoff in October 2023, they have been involved in various innovations within this field, which may include patents related to quantum algorithms, quantum cryptography, quantum communication, and systems for quantum computing.

The specific details about their patents would typically involve technical descriptions of their inventions, claims defining the scope of these inventions, and applications in quantum technology. For the most accurate and up-to-date information regarding their patents, including patent numbers and detailed descriptions, I recommend visiting the official United States Patent and Trademark Office (USPTO) website or similar patent databases.
This patent describes a method for bonding a semiconductor chip to an organic laminate substrate. At a specific bonding temperature, solder is used to attach the chip to the substrate. Without allowing the assembly to cool, underfill is dispensed between the chip and substrate, followed by curing at a higher temperature. Another method detailed involves applying solder to the substrate’s pads and chip pillars, enabling bonding through direct contact.
IBM scientists wrote this patent to cover a technique for connecting physical and virtual environments through quantum entanglement. It captures video of a physical object and detects a feature in the footage. A first qubit is encoded based on the feature’s value, and is then entangled with a second qubit, forming a qubit pair. The second qubit’s quantum state informs the rendering of a virtual object corresponding to the physical one, creating a synchronized virtual environment.
This patent presents techniques for mitigating cross-resonance collisions in qubits using Stark tone pulses. A tone management component manages the application of pulses by a tone generator to prevent frequency collisions. The tone generator can apply an off-resonant tone pulse to a qubit, inducing a Stark shift, and a cross-resonance tone pulse to a control qubit, which can also affect its frequency. The patent also outlines various types of gates, such as cross-resonance, two-qubit, and measurement gates, which can use echo sequences or other techniques.
