Working Lunch

Thursday, December 26, 2024

It's lunchtime, Chicago.

Sales rose this year during the holiday shopping season despite the fact that Americans faced elevated prices for many groceries and other necessities, according to new data.

Holiday sales from the beginning of November through Christmas Eve climbed 3.8%, outpacing the 3.1% increase from a year earlier, according to Mastercard SpendingPulse, which tracks all kinds of payments including cash and debit cards. The last five days of the season accounted for 10% of the spending.

And, instead of building a small-scale quantum computer designed primarily for testing and public demonstrations, PsiQuantum, the anchor tenant at the Illinois Quantum and Microelectronics Park, is shooting for the moon with a 1 million-quantum-bit machine capable of tackling practical, real-world applications.

It’s a future that even leading scientists aren’t sure is possible. But PsiQuantum co-founder Pete Shadbolt intends to prove that it is.

Read that story and more in today's Working Lunch.
