The researchers demonstrated AQT’s effectiveness by exploiting entanglement—one of the basic concepts of quantum physics in which the properties of one particle affect the properties of another, even when the particles are separated by a large distance. The researchers were able to use AQT to transfer one electron’s quantum spin state across a chain of four electrons in semiconductor quantum dots—tiny, nanoscale semiconductors with remarkable properties. This is the longest chain over which a spin state has ever been transferred, tying the record set by the researchers in a previous Nature paper.

Researchers and companies have developed an increasing number of devices that deliver proofs-of-concept for the practical application of quantum hardware (see for example Almudever et al. 2020). However, research does not only push ahead concerning the production of quantum hardware. The development of applicable quantum software that can run on these quantum machines, enabling quantum advantage, sees progress as well. You may be surprised to learn that our enterprise customers have already built hundreds of quantum applications across many industries. Blockchain is a record-keeping technology designed to make it impossible to hack the system or forge the data stored on… Read More

As an example, suppose that a customer visits a website for information on renting. The customer can’t decide between a studio or one-bedroom apartment, so she searches for more information on both and cannot find any definitive information. In this case, the “next best offer” could be to create a personalized email with links to articles and videos from both types of apartments, so the customer can decide which one is better for her. A loyalty program is a reward program that gives points or other awards to customers who shop at a particular establishment. A typical example might be… Read More
