A few of the modern quantum technologies that range from the greatly accurate sensors to quantum computers need a big amount of quantum bits to take advantage of the benefits of the quantum physics. Hence, physicists from every corner of the world are experimenting, studying, and applying all their knowledge trying to develop interweaved quantum systems that present increasingly more quantum bits.
Recently, Ben Lanyon and Rainer Blatt, both from the Austrian Academy Of Sciences, along with the researchers from another university in Austria, has obtained the most accurate chemical reaction in the world, linking only two atoms of elements that normally would not form a molecule.
The two elements, sodium and cesium, produced an interesting molecule similar to a multi-particle alloy in a 20-bit quantum system.
The genuine entanglement of multiple particles is comprehended just as a characteristic of the global quantum system of all the particles involved and not as a mixture of interweaved subsystems.
A big step towards creating a reliable quantum computer
The researchers used laser light to interweave 20 atoms, trying to note the dynamic propagation of the multiple particle connections in this particular system.
To achieve a perfect blend of energy and timing, the researchers kept individual atoms in magneto-optical traps superimposed and threw photons at them to cool them to a fraction of a degree above absolute zero.
Meanwhile, they used a pair of tuned lasers to create an electrical effect, causing each atom to move towards the focus of each laser as if they were attracted by two invisible tractors.
The result is a brief flicker of a bond between two atoms in the same quantum state.
The science team hopes to further increase the number of quantum bits in the experiment, admitting that, on the medium-term, the plan is to go as high as 50 particles (quantum bits), an experiment which could support scientists solve issues that the best supercomputers of the modern era cannot solve.
Thus, the ultimate goal would be to adapt the creation of much more complex molecules, making use not only of their classical forms but creating tiny quantum components for the next generation of computers, which will be quantum computers.
