As a child growing up in India, through *Amar Chitra Katha* comic series, like many other kids, I was introduced to:

The

( पञ्चतन्त्र, “Five Treatises”) is an ancient Indian collection of interrelated animal fables in Sanskrit verse and prose, arranged within a frame story. The surviving work is dated to roughly 200 BCE – 300 CE, based on older oral tradition.Panchatantra

This was an attempt, I understand now, to make us *street-smart* and be successful in the *material, practical world*. What I found quite appealing, additionally, was its * structure* –

*it was story within a story*, like a

*Russian doll*–

*mise en abyme*.

This **lower knowledge** was complemented with **higher knowledge**, *book-smarts*, for *spiritual success*:

The

Upanishads(उपनिषद्Upaniṣad) are late Vedic Sanskrit texts of Hindu philosophy which form the foundations of Hinduism. They played an important role in the development of spiritual ideas in ancient India, marking a transition from Vedic ritualism to new ideas and institutions.

To be clear:

You don’t read *Upanishads* to become a tech-entrepreneur.

You become a tech-entrepreneur to read *Upanishads*.

There are many *Upanishads*; I mentioned *Mundaka* earlier in Weston Brahmin. For this post, I decided this one is more appropriate (also from *Atharva Veda*):

The

Prashnopanishad(प्रश्नोपनिषद्,Praśnopaniṣad) is aMukhya(primary) Upanishad, and is listed as number 4 in the canon of 108 Upanishads of Hinduism. It contains sixPrashna(questions), and each is a chapter with a discussion of answers.

Beyond the structure, what is notable about this *Upanishad* is that it most directly discusses the **primal energy** (*Prana*) and **form-giving substance** (*Rayi*), which, in my view was a valiant attempt to understand *Life-Physics* (a phrase that I just coined).

Best I stick to *inanimate* objects, in my view, that is, *Theoretical Physics*.

Beyond *energy-matter *discussions (which is quite old news, clearly), I felt it is time (for OR/OM folks in particular, but in general for folks with curiosity about *Quantum*) to become familiar with something that is considered *even more fundamental*. ** Which is? **Channeling

**Sean Connery**(see my post The Artist of Bond):

Information. *Quantum* Information.

It has been nearly two millenia since the last *Upanishad* was written, in *Sanskrit*, many in the form of *shlokas*. That was the *lingua franca* of that age among the priestly class. Today, in the Universities around the world, including India, it is *Mathematics*, in the form of *formulations*. The *frame* I am using is *Neo-Quantum Organon*, and I chose *Latin* because that was the* lingua franca* for scientific communication in Europe, post-Enlightenment, notably (a valiant effort at understanding *inanimate* Universe):

(Philosophiæ Naturalis Principia MathematicaMathematical Principles of Natural Philosophy) byIsaac Newton, often referred to as simply the(/prɪnˈsɪpiə, prɪnˈkɪpiə/), is a work in three books written inPrincipia, first published 5 July 1687. After annotating and correcting his personal copy of the first edition, Newton published two further editions, during 1713 with errors of the 1687 corrected, and an improved version of 1726.Latin

In my post, as COVID19 began – What would Newton do? – I summarized:

Social Distancing. Mathematical Research.

I actually did that! A prerequisite to be able to follow

Neo-Quantum Organon, Book Three: Quantum Queuing (QuQu)

is a working knowledge of both *Quantum Information Theory* (which most OR/OM folks do* not *have) and *Queuing Theory* (which most OR/OM folks should have).

The *Five Questions* posed introduce *Quantum Information Theory* to OR/OM folks through *Semi-Definite Program (SDP) formulations, as a bridge from OR/OM to Theoretical Physics, *cheekily referring to it here as:

Pancha-Prashna Q-Upanishad.

Beyond simple examples with closed form solutions via algebraic manipulations, most interesting settings require numerical computation, and so we have created companion *Jupyter* notebooks.

The first question on *Quantum State Discrimination*, I have discussed earlier as a *Śrīdhara Brāhmaṇa*.

The second question is on *Quantum State Fidelity*. Given two *mixed states*:

How close are they to each other?

A measure of closeness is *fidelity*. Two identical states have fidelity of one; orthogonal states have zero fidelity. There is a semi-definite characterization, and *fidelity* is the optimum value of certain primal and dual semi-definite programs.

With respect to *Quantum Channel Discrimination*, our third *prashna*, we want to know what is the *maximum probability* of distinguishing * without* using

**entanglement**, and what additional sharpening is possible

**with entanglement**. This is where the real fun begins in

*quantum information theory*. Again, this admits a SDP formulation.

Question 4 simply wonders *if a given state is separable or entangled*. It turns out that this is not that easy to determine! SDP to the rescue, again. Question 5 brings us to the very core of *Quantum Shannon Theory*:

What is the maximum achievable transmission rate through a noisy quantum channel?

** QuQu** focuses on this fundamental practical question in

*Quantum Communication*, building on

*Quantum Shannon Theory*, merging it with

*Queuing Models*:

Since quantum information *decoheres* with time, and sending more information causes *queuing delays*, due to *buffering*, what is the maximum information that can be sent?

*Seriously*, isn’t this intellectual *fun*? 🤷🏽♂️

Right now, applying a *maximally inverse* tactic to my own weekend pastimes, I am off to see *F9: The Fast Saga* on Cinemark XD, for ** ample non-intellectual **entertainment. 😏

(also known asF9andF9: The Fast Saga) is an action film, with stars Vin Diesel, Michelle Rodriguez, Tyrese Gibson, Ludacris, John Cena, Jordana Brewster, Nathalie Emmanuel, Sung Kang, Michael Rooker, Helen Mirren, Kurt Russell, and Charlize Theron. In a limited release, it has already grossed over $300 million, on a budget of $200 million.Fast & Furious 9
