It could happen if the tunnel is long enough, but the chances are basically zero
How much time does it take to send a package from New York to Tel Aviv, and how does that compare with sending an email from one side of the Weizmann Institute of Science campus to the other? Now shrink the package down to the size of one of the electrons making up the email and put up an impenetrable barrier over the ocean. The “package” electron could make the crossing faster, even breaking the light “speed limit.” Prof. Eli Pollak, together with postdoctoral fellow Dr. Tom Rivlin, both of the Weizmann Institute’s Chemical and Biological Physics Department, and Prof. Randall Dumont of McMaster University in Canada, recently provided theoretical support for this idea.

New Views of Quantum Jumps Challenge Core Tenets of Physics
One of the most basic processes in all of nature a subatomic particle’s transition between discrete energy states is surprisingly complex and sometimes predictable, recent work shows

Quantum mechanics, the theory that describes the physics of the universe at very small scales, is notorious for defying common sense. Consider, for instance, the way that standard interpretations of the theory suggest change occurs in the quantum turf: shifts from one state to another supposedly happen unpredictably and instantaneously. Put another way, if events in our familiar world unfolded similarly to those within atoms, we would expect to routinely see batter becoming a fully baked cake without passing through any intermediate steps. Everyday experience, of course, tells us this is not the case, but for the less accessible microscopic realm, the true nature of such “quantum jumps” has been a majo

Israel is closing in on half a million COVID-19 inoculations, Health Minister Yuli Edelstein said Monday night. The Jewish state entered its third national lockdown on Sunday in an effort to lower infection rates while the vaccination campaign ramps up.
A record 99,000 people were vaccinated on Sunday, bringing the national total to 379,000. Edelstein has indicated that a new record of over 100,000 citizens were given shots on Monday. Israel is currently leading the world in vaccinations per capita.
The country began its inoculation drive last week, focusing on healthcare workers, people over 60, and groups considered to be at risk.
Provided that Israel maintains this week’s rate of daily inoculations, it will see a dramatic easing of the coronavirus crisis next month, said Eran Segal, a biologist at the Weizmann Institute of Science who has been mapping and analyzing the impact of the pandemic.

Israel is closing in on half a million vaccinated, Health Minister Yuli Edelstein said Monday night, as it continues to accelerate the rate at which it is inoculating citizens against COVID-19. Health Ministry figures Tuesday morning confirmed this, putting the number vaccinated at 495,000 more than 1 in 20 Israelis.
Israel began its vaccination drive on December 20, focusing on healthcare workers, over 60s, and at-risk groups, and is leading the world in vaccinations per capita. A record 99,000 people were vaccinated on Sunday, bringing the national total to 379,000, and Edelstein indicated that a new record of over 100,000 were given shots on Monday.
