To USB or Not to USB


Wireless, Quantum Computing, and a USB Type-C

Wireless, Quantum Computing, and a USB Type-C

The ultimate in quantum computing is wireless communications.

(Really there’s a lot more than that).

The idea is that if I can get the particles in California entangled with particles in China, I could have instaneous communication. (I don’t know how much power it would take, if it would require a solar farm the size of Texas all the time, or a a bunch of power initially but I digress.)


Turns out the Chinese have already demonstrated something like this during their summer vacation.

It’s years from commercialization (if ever).


You can wirelessly charge devices and your iPhone today


The new iPhones have glass backs so they can charge your phone wirelessly. The wireless charging bases cost from 30-60 dollars or more and can provide 10W and sometimes more.

The disadvantage is the number of watts they can provide for the cost.


The fact is the physics of a wired connection (at least for now) provide the fastest, cheapest power transfer especially using USB Type-C. The chargers are cheaper, the wires are cheaper (unless you buy the Apple branded stuff and let’s face it, the Apple stuff is still probably the safest and most reliable.

So Wired USB charging is here to stay for a long time. Especially with the USB Power Delivery options available which will pretty much change even many household items to use USB.


Enabling Type-C with Software and Standards

Both Google and Microsoft and the USB-IF (yes, I can’t count) have been working hard to standardize the Type-C convention for easier implementation.

Together, they defined the USB Type C Connector System Software Interface (UCSI). This describes the register and data structures for use in the drivers and the OS Policy Manager to interface to Type-C connectors.  Revision 1.1 was released in August.

It also defines a hardware connection/signal as well for the SoC to talk to the Type-C hardware which is either in a PMIC or stand-alone Type-C Port Controller.


The advantage of this is Android and Microsoft already follow the UCSI standards and have drivers and pieces to speed the proper deployment. This standardization reduced the problem set for everyone building Type C products. (We can make some kind of assumption Apple probably has either followed UCSI or has implemented a proprietary version since it’s a closed OS).


This allows Type-C implementers of SoCs using Android or Microsft can focus on the hardware implementations and some of the software drivers using UCSI. (Standard APIs good for adoption).



Apple’s Time Travel Project


I’ve been reading this book called “The Fold” and another “Depature” which deal with quantum mechanics. I decided after reading these two books that Apple has probably built some sort of time travel device based on quantum mechanics and a linear accelerator (which is obviously why their building is a circle, or they are building a new power source for Iron Man)

It turns out some scientist worked out a way to build a closed-loop quantum computer which would allow you to send a quantum computer back in time and use it to solve a problem because it wouldn’t be touched by the past, and would (I think) when it reentered the current time have solved whatever problem you had it working on.

It is hilarious to me that scientists actually say things like “in reality we don’t know we can build a time traveling quantum computer”

Doctor Who featured something like this, but used actual time travel. (well as actual as time travel can be in a fictional setting).



Here’s what XKCD has to say about time travel.
