Quantum computation has long been annunciate as “ just around the corner , ” but several company are now determined to make this a commercial-grade reality , with the hope of solve complex problems beyond classical computer ’ reach .
The problem in question are astray - ranging , from medicament and cybersecurity to material scientific discipline and interpersonal chemistry . But first , there are very practical problems to be solved , such as develop chips that can dependably host large numbers of qubits — short for quantum spot , the fundamental unit of information in quantum computing .
As usual in a in high spirits - stakes tech race with an unsettled time horizon , technical school giants such as Google and Microsoft are at the cutting edge . Yet startup are also pose to dally an important part , specially tackle constriction like connectivity and error rectification that are decisive for scaling quantum systems .
But some inauguration and humble tech companies are taking on the microprocessor chip challenge head - on and deserve mention alongside the more care - grabbing efforts from industriousness whale . While Big Tech project typically boast the highest qubit count , rethinking designs from first principles and using dissimilar approaches could yield equally promising results .
Here are some of the companies behind the independent quantum potato chip projection that are worth tracking .
Akhetonics
Akhetonicsis a German photonics startup working on anall - visual , general - purpose chip — a contrarian bet in a field where most focalize on narrow applications .
