IBM researchers demonstrate the quantum advantage over classical computing

IBM researchers have finally proven in a real-world experiment that quantum computers are superior to classical devices – although for now, only at a miniature scale. 

Big Blue’s quantum team set out to discover if today’s quantum devices, despite their limitations, could be used to complete a task that cannot be done on a classical system.  

Since quantum computing is still in its infancy, the researchers leveled the playing field between the two methods by designing a microscopic experiment with limited space – that is, limited amount of available memory.

IBM claimed to have made the world’s first 2nm chip

IBM claims that the 2nm chip could achieve 45 percent higher performance, or 75 percent lower energy use, than “today’s most advanced 7nm node chips.”

Darío Gil, SVP and director of IBM Research.

A single human hair spans a whopping 50,000-75,000 nanometers. A human red blood cell is 6,000-8,000nm. Covid-19 is 50-140nm…….. To build nodes 3nm and below requires extremely expensive and sensitive equipment, and a rethink on how nodes are laid out – hence the different metrics now used to measure smaller nodes.

IBM Singapore Supercomputing Virtual Forum 30 June 2020

Overview:

In the past few months, technology has been put on a test like never before. On one hand healthcare research professionals have be grappling with the onset of a pandemic, trying to find answers in data and numbers. On the other hand, corporates are struggling to make sure that continuity is maintained in order to minimize long term economic impact. In some form or the other, both segments are embracing technology for a better future. Join us for this virtual summit where we bring in the experts from the domain of HPC, AI and Quantum to explore how the paradigm has shifted from what we ‘want’ to what we ‘essentially need’ from Tech for Good.

Trying to allocate 1005 pages for VMLINUZ error when booting with RHEL or CentOS 6.5 disks

VMLINUZ2

I was booting the RHEL 6.5 or CentOS 6.5 on a IBM PureFlex System and I have this error. This occurs when When installing Red Hat Enterprise Linux 6 from DVD media the installation will default to native Extensible Firmware Interface (EFI) mode boot. I do not have

According to IBM Website,

The workaround is simply to install the operating system in the traditional legacy mode, since there is generally no reason to install in other than Legacy mode. The workaround is only necessary if the media you are booting defaults to EFI mode (DVD or EFI Preboot eXecution Environment (PXE)) otherwise a legacy installation (e.g. – traditional PXE) is the default and is unaffected by this issue.

To force a legacy installation of the operating system from the EFI bootable DVD media the user should:

Press F12 key when the IBM splash screen is shown during system boot.
Select Legacy Only option and press Enter.
The operating system will boot and install in traditional legacy boot mode.

And the issue was resolved.

News from IBM on Quantum Computing

Quiskit

Quiskit – the “Quantum Information Science Kit” SDK is an open source platform that allows developers and coders familiar with Python and Jupyter Notebooks to program our quantum computers https://github.com/Qiskit

  • QISKit AQUA builds and runs algorithms, and contains algorithms and domain-specific tools, making it possible to run classical computing applications on quantum computers, as well as for others to build their own applications. Aqua is one of four Qiskit elements:
  • Qiskit Terra: the ‘earth’ element, is the foundation on which the rest of the software lies. Terra provides a bedrock for composing quantum programs at the level of circuits and pulses.Qiskit Ignis: the ‘fire’ element, is dedicated to fighting noise and errors and to forging a new path. This includes better characterization of errors, improving gates, and computing in the presence of noise.
  • Qiskit Aer: the ‘air’ element, permeates all Qiskit elements. To really speed up development of quantum computers we need better simulators, emulators and debuggers.
