Are You Ready for the Quantum Computing Revolution?  Quantum physics has already changed our lives. Thanks to the invention of the laser and the transistor — both products of quantum theory — almost every electronic device we use today is an example of quantum physics in action. We may now be on the brink of a second quantum revolution as we attempt to harness even more of the power of the quantum world. ......... Although quantum theory is over a century old, the current quantum revolution is based on the more recent realization that uncertainty — a fundamental property of quantum particles — can be a powerful resource. ............  In the quantum world, we must use the language of probability, rather than certainty. ......... the revolutionary idea behind quantum information processing is that quantum uncertainty — a fuzzy in-between “superposition” of 0 and 1 — is actually not a bug, but a feature. It provides new levers for more powerful ways to communicate and process data. .............. While mathematical encryption techniques are vulnerable to being cracked by powerful enough computers, cracking quantum encryption would require violating the laws of physics. ............  quantum computers are fundamentally different from current classical computers. The two are as different as a car and a horse and cart. A car is based on harnessing different laws of physics compared to a horse and cart. It gets you to your destination faster and to new destinations previously out of reach. ............ quantum teleportation, where information encoded in quantum particles disappears in one location and is exactly (but not instantaneously) recreated in another location far away. While that sounds like sci-fi, this new form of data transmission could be a vital component of a future quantum internet. .............  A particularly important application of quantum computers might be to simulate and analyze molecules for drug development and materials design. ..........  solving complex optimization tasks and performing fast searches of unsorted data ............  Given the current state of the field, it’s not clear when or if the full power of quantum computing will be accessible. ............ Nobody could have predicted the myriad ways that classical computers impact every aspect of our lives. Predicting quantum applications is equally challenging.  

Coronavirus cabinet concludes: Full lockdown beginning Friday Blue and White ministers accuse PM of using closure to mute protesters · Nearly 7,000 people diagnosed in one day ............  The country is heading back into a complete lockdown which is to begin Friday and is likely to last until at least the end of the holidays. .......... The lockdown is expected to be more stringent than the one in March, and should include shuttering synagogues, reducing the number of people who can protest, closing all nonessential businesses and markets, reducing public transportation routes and allowing citizens to gather only within their nuclear families. ........... The decision comes on the day that almost 7,000 people were diagnosed with coronavirus in a 24-hour period – unprecedented numbers. ...........  The closure will cost an estimated NIS 35 billion ($10b.) if the lockdown lasts three weeks. .............  There were 6,948 people diagnosed with the virus on Tuesday, the Health Ministry showed Wednesday evening – some 11.7% of the 61,165 people screened. Israel has now had 203,136 cases since the start of the pandemic ........... new restrictions to stop the coronavirus from burning across the country ............   “I am fighting for the lives of the citizens of Israel... We are at war – wake up!”
