#Quantum – Do you need more than 50 #Qubits? Google may help you

Hi !

Today I need to to comment on a new that will make some noise:

A Preview of Bristlecone, Google’s New Quantum Processor

TLTR:

Google announced its new Quantum chip named [Bristlecone]. Interesting detail, it has 72 Qubits, and leaves behind the (until now leader) chip built by IBM with 50 Qubits.

At this point the interesting thing will be to see how Google handles error correction issues at that scale. Remember that when you increase the number of Qubits, the probability of having “dirty” data or unreliable information grows exponentially.

The important thing in this point, is that when passing the limit of 50 Qubits,
Google positions this chip as the first to present battle to the super computers we currently have. Before many get a good scare, it should be noted that a chip of these capabilities, on passes to the current super computers in only certain types of tasks.

As well, it is time to continue study quantum models and computing and to start making bets for 2020!

Happy QCoding!

#Quantum – Necesitas mas de 50 #Qubits? Google te los trae en bandeja

Buenas!

Hoy toca comentar una noticia que dará que hablar:

A Preview of Bristlecone, Google’s New Quantum Processor

Os voy a ahorrar la lectura técnica:

Google anunció su nuevo Quantum chip llamado [Bristlecone]. Detalle interesante, el mismo posee 72 Qubits, y deja atrás al (hasta ahora líder) chip construido por IBM con 50 Qubits.

En este punto lo interesante será ver como Google maneja los índices de errores a esa escala, cabe recordar que al subir el numero de Qubits, la probabilidad de tener datos “sucios” o información no fiable crece exponencialmente.

Lo importante en este punto, es que al pasar del límite de los 50 Qubits, Google posiciona a este chip como el primero en presentar batalla a los super ordenadores que tenemos actualmente. Antes de que muchos se lleven un buen susto, hay que remarcar que un chip de estas capacidades, sobre pasa a los super ordenadores actuales en solo determinados tipos de tareas.

Pues bien, a seguir dedicándole un poco de tiempo a estudiar modelos cuánticos y a comenzar a hacer apuestas para el 2020!
