Could B team detect the moment a connection was lost?

If team A takes a secret measurement at 10 am there's no way team B would know what time it was taken?

Then it is possible to send information by knowing exactly when the measurement was being conducted. As long as both groups have clocks that are synchronized then a 1/0 could be transferred based on the timing of the measurement.

Would the other side know exactly when the measurement was being conducted?

Won't the other particle be effected (in a detectable way) when the first one is measured?

As long as the effect can be detected then information could be sent.

Left spin = zero

Right spin = one

Time to go binary... 01101000101011... all over again.

Someone's been bullshitting people for years into believing that quantum entangled particles would change their combined spin instantly across any distance.

Bell tests have been performed where the locations were sufficiently separated that communications at the speed of light would have taken longer—in one case, 10,000 times longer—than the interval between the measurements.[7][6]

Is this the quantum entanglement that relays information instantaneously across any distance?
